Học Để Thi reporter in Minneapolis: I've never seen anything like this
Minneapolis Mayor Jacob Frey was one of the first local officials to face a "Defund the Police" backlash earlier this month after he wouldn't endorse calls from members of the city council and activists to completely dismantle the Minneapolis Police Department. Frey was asked point-blank if he would back the dismantling of the police department while addressing a crowd of protesters.
Minneapolis Mayor Jacob Frey showed up today at the protests. He was asked if he would commit to abolishing/defunding the police. Incredible to witness crowd hold him directly accountable. Man did a literal walk of shame.— Heidi Heitkamp (@HeitkampHeidi) June 30, 2020

"I do not support the full abolition of the Minneapolis Police Department," Frey says.
"Alright, then get the f--- out of here," the protest leader yelled at him. "Go."
The council last week voted unanimously to remove the mandate in the city's charter that it maintain a police department, the first step in their plan to replace it with a Department of Community Safety and Violence Prevention, “which will have responsibility for public safety services prioritizing a holistic, public health-oriented approach,” a draft of the amendment said.
While most widespread protests -- which in the early days coincided with violent riots, largely in big cities and mainly after dark, even as many protests were peaceful -- have abated since late May and early June, activists have capitalized on the wave of public opinion to extract action from politicians everywhere from the White House to city hall. They've also seen huge fundraising windfalls as people have been eager to give to causes like Black Lives Matter and bail funds, which fight against racial inequality and police brutality.
One GoFundMe page associated with the Black Lives Matter Los Angeles chapter, for example, had been in existence since 2018 and as of the beginning of June had raised about $615,000. In less than four weeks, it's skyrocketed to over $2.4 million.
And The National Bail Fund Network, which essentially serves as a directory for local groups that help disadvantaged people afford bail, has seen its organizations raise more than $75 million in recent weeks, according to a spokesperson. In a three-week period, that spokesperson says, "many individual bail funds have seen an increase of 100-200 times last year's annual fundraising amount."
On Sunday, Mississippi lawmakers voted to remove the Confederate battle emblem from the state flag.
The bill calling for its removal passed 91-23 in the state House and 37-14 in the state Senate.
Before Sunday's vote, Mississippi's state flag was the only state banner remaining in the country that still depicted an overt Confederate symbol, according to the New York Times. (The emblem has remained on the state flag for 126 years.)
Now, the bill is off to Republican Governor Tate Reeves, who has expressed that he will sign it.
A commission in charge of the flag's redesign will also be formed, per the bill's language, and Mississippi voters will need to approve it in November. (If rejected, the commission will draft another redesign, to be presented to the Legislature in 2021.)
Past attempts to change the flag, such as a 2001 public referendum, have not gone through.
The decision comes at a time of deep reckoning with the country's racist past and present, in light of protests against the racism and police violence experienced by Black Americans.
Ahead of the vote, prominent figures and institutions weighed in: The NCAA, the collegiate sports organization, announced earlier this month that states in which the Confederate flag had a "prominent presence" would be barred from hosting championship games.
Walmart, the retail giant, removed the Mississippi state flag from display in its stores on June 23. Others, such as country singer and Mississippi native Faith Hill, directly called for the flag's removal.
Amid recent, ongoing protests for the Black Lives Matter movement, calls for the removal of Confederate statues, symbols, and names have abounded.
At some demonstrations, protesters have taken matters into their own hands, using a variety of tactics to remove statues depicting slaveholders, colonizers, and figures of the Confederacy.
The Mississippi vote formalizes a similar push.
In a statement before the vote, Democratic state senator Derrick Simmons encouraged colleagues to cast their votes for the "Mississippi of tomorrow," according to NBC News.
"In the name of history, I stand for my two sons, who are one and six years old, who should be educated in schools and be able to frequent businesses and express their Black voices in public places that all fly a symbol of love, not hate," Simmons said.

Kylin Hill, a running back for the Mississippi State Bulldogs, said he would not play for the Bulldogs unless the flag was changed. Other sports figures in Mississippi, including coaches like University of Mississippi's Lane Kiffin and Mississippi State's Mike Leach, also pushed for a change to the flag.

Breacking News: Dixie Chicks change their name because…RACISM
Across the band's social media pages, the women now go by The Chicks. On Thursday morning, their official Twitter handle was changed from @dixiechicks to @thechicks.
The group made up of Natalie Maines, Martie Erwin Maguire, and Emily Strayer, also changed their name on Instagram and Facebook.
A statement on The Chicks' website said “We want to meet this moment.” The term Dixie refers to Southern U.S. states, especially those that belonged to the Confederacy.
The Chicks also dropped a new song “March March" from their comeback album "Gaslighter" that features videos and images from the recent Black Lives Matter rallies.
In early July, fellow country band Lady Antebellum announced on social media that it changed its name to Lady A.
The decision, which the Grammy-winning group announced on Twitter, comes "after much personal reflection" and conversations with "closest black friends" as Antebellum refers to a period of time "which includes slavery."
Band members, Hillary Scott, Charles Kelley, and Dave Haywood, said in a statement they are regretful and embarrassed for not taking into consideration the word’s associations with slavery.
The statement said that they chose the name after the antebellum-style home where they shot their first band photos, and it reminded them of Southern styles of music.
Dear fans... pic.twitter.com/7JlcH2NMl6— Lady A (@ladya) June 11, 2020
But they said in recent weeks, their eyes have been opened to “blindspots we didn't even know existed" and "the injustices, inequality and biases black women and men have always faced."
The Chicks. It’s their name and they can change it if they want to change it. But seriously, this ‘erasing’ of history and everything that goes along with it seems truly dangerous, especially when we know the people at the center of this movement have their own socialist/communist agenda.
There’s a young lady from Venezuela that’s getting a lot of attention lately for pointing out that this madness is exactly what they did in Venezuela in order to turn the country into the socialist utopia it has become:

Beauty and a brain. I think I’m in love…
In any event, all of this kowtowing to “this moment” is just feeding the protests, the violence and the overt push to the far left. I just really hate to see it.

Đánh giá OPPO Find X2 tốt hơn iPhone 8 Plus
Máy này mình mua hộ chị mình và có khoảng 1 tuần trải nghiệm, chị đang sài 8+ vì lý do công việc nên sài iphone không tiện và muốn sử dụng flagship android làm máy chính. Với giá này thường thì sẽ chọn samsung hoặc huawei mà cay ở chỗ cả hai máy đều không sử dụng chip snap, thế nên mình chọn oppo ( chị mình vẫn nghĩ oppo là máy mỹ). Thật sự rất hài lòng với sản phẩm máy mượt, pin ổn, màn hình đẹp, cam tốt, sạc nhanh, 120hz, quay video chống rung tốt, chụp đêm ảo vồn. Máy vẫn gặp hiện tượng tụt pin khi để qua đêm nhưng bù lại máy lại cho tốc độ sạc nhanh kinh khủng mình sạc 20 phút là đủ sài 1 ngày không chơi game, 12gb ram mà không cho đa nhiệm quá nhiều ứng dụng ☹ bạn nào edit video chắc sẽ cần chứ mình không tài nào sử dụng quá 6gb. Mình không nhận quà tai nghe mà lấy phiếu mua hàng sắm con Sony WF-1000XM3 ( thêm tí lúa ). Lời khuyên là mới mua về nên đi dán PDF chứ nó xước thì sót lắm, sử dụng một thời gian thì nên đi thay dán màn hình chứ miếng dán tặng kèm xước be bét, máy này bật dark mode pin trâu hơn. Chốt anh em nào có nhiều tiền thì nên mua máy cho trải nghiệm mượt mà với con chip đầu bản, cũng nhờ đó mà mình có 8+ sài (--").

Stacey Abrams told: President Trump wouldn't rename military bases because he wants to hold up Confederate figures and others who engaged in what she called domestic terrorism.
"The View" co-host Joy Behar had asked Abrams about the White House's decision not to rename military bases named after Confederate figures.
"Why is he doing that?" Behar asked. "We know he's appealing to his base. Is there any other reason why he would be doing something like that?"
.@staceyabrams on Pres. Trump's refusal to rename military bases named after Confederate figures: "It's part of his narrative, to continue to lift up those who were strongmen, who used their domestic terrorism to rip our nation apart." https://t.co/ls9Uu3ab0c pic.twitter.com/DGdXk4vhmR— Heidi Heitkamp (@HeitkampHeidi) June 11, 2020
"It flows through how we run our elections, how we issue resources, it's part of how they treated the Census, and it's part of the resistance to acknowledging that this nation has a problem with systemic racism," she said.
Her comments came amid ongoing protests surrounding George Floyd's police-involved death and opposition to the idea of public property bearing the name of Confederate figures. Before Abrams' interview, Behar called Trump a "domestic terrorist" but walked it back after being prompted by co-host Whoopi Goldberg.
Trump had accused Washington state of not doing enough to counter "domestic terrorists" in Seattle, a label "The View" hosts said was inappropriate.

"The View" co-host Meghan McCain claims push to 'defund the police' is helping Trump reelection bid
Meghan McCain warned on Tuesday that Democrats were hurting their party's electoral prospects by countenancing the idea that local governments should "defund the police" after George Floyd's death.
"If you're explaining, you're losing and there's a lot of explaining going on on this," McCain said. "... If you mean reform, say 'reform.' If you mean defund, say 'defund.' People are confused."\
“If you’re explaining, you’re losing, and there’s a lot of explaining going on,” says of the defund the police movement. “If you mean reform, say reform. If you mean defund, say defund. People are confused.”— Heidi Heitkamp (@HeitkampHeidi) June 10, 2020
“This is giving Trump a great campaign slogan.” https://t.co/aRJ9aoShW2 pic.twitter.com/vHV6Q8WRsb
McCain noted that Rep. Ilhan Omar, D-Minn., had called for the dismantling of the Minneapolis police department, which employed the officer who knelt on Floyd's neck for more than 8 minutes on May 25. Floyd died soon after and the former officer, Kenneth Chauvin, faces murder charges.
"Listen, you guys can spin and say everything you want," she told her fellow "View" co-hosts. "I know that politics at the end of the day, unfortunately, is real simple and it is about slogans. And 'defund the police' is a great one for the Trump campaign."
Earlier, co-host Sunny Hostin had pushed back on the idea that "defund the police" could be relegated to a "slogan."
"The biggest misunderstanding is that people think that defunding the police means abolishing the police and that's not true," she said. "There are three different reactions to what you can do in terms of combatting police brutality, especially police brutality in black and brown communities ... You can either reform the police departments, you can either defund the police departments, or you can disband the police departments."
Hostin added that when reforms like implicit bias training don't seem to work, the next step would be to transfer money from the police departments to social services.
"The last and most rarest form of combatting police brutality is disbanding police departments," she said. "It is rarely done. It was done in, I think about seven years ago, in Camden, New Jersey. What happened there is, it's disbanded.
"Officers are then basically -- they re-apply for their positions. People in the community re-apply for their positions and police safety -- public safety --they're retrained, but it looks very different," she continued. "It's reimagined. Again, it's so rare that it's only been done a handful of times really, and it hasn't really been done in big metropolitan cities.
"But it's an option that people are now considering. This discussion, by the way, was going on when I was a community prosecutor in the late '90s. [Former New York City Police Commissioner and LAPD Chief] Bill Bratton said yesterday it's been going on for about 50 years or more. So, this is not a new discussion and I'm surprised people are relegating it to a slogan because that's not what this is about. This is about saving lives."
