Capitol riots: Black Americans decry police double standards
Black Americans are calling out double standards over use of force by police during protests in Washington DC last week, which led to the storming of the Capitol.

The amendment was ratified in 1967 - four years after the assassination of John F Kennedy - and was intended to address questions of presidential succession, should a president become incapacitated.
And for this reason, a number of presidents have used the amendment - specifically section three - which allows them to temporarily hand over power to their vice-presidents.
In 2002 and 2007, President George W Bush placed his vice-president in charge when he was sedated during routine colonoscopies. President Ronald Reagan did the same in 1985 when he was in hospital for cancer surgery.
But to date, no sitting president has ever been permanently removed using the 25th Amendment.

He hadn't won. There was no victory to steal. But to many of his most fervent supporters, these facts didn't matter, and still don't.
Sixty-five days later, a motley coalition of rioters stormed the US Capitol building. They included believers in the QAnon conspiracy theory, members of "Stop the Steal" groups, far-right activists, online trolls and others.
The violence in Washington shocked the world and seemed to catch the authorities off guard.
But for anyone who had been carefully watching the unfolding story - online and on the streets of American cities - it came as no surprise.

US First Lady Melania Trump has issued a statement, saying she is "disheartened and disappointed" with events last week, external.
But she also said she had been the victim of personal attacks since the storming of the Capitol.
"I find it shameful that surrounding these tragic events there has been salacious gossip, unwarranted personal attacks, and false misleading accusations on me - from people who are looking to be relevant and have an agenda," she said.
"This time is solely about healing our country and its citizens. It should not be used for personal gain."
Mrs Trump thanked "the millions of Americans who supported my husband and me over the past four years and shown the incredible impact of the American spirit".

Mr Burns has a career spanning 33 years with the State Department. He's a former ambassador to Russia and Jordan, and served as a Deputy Secretary of State under President Obama.
At present, he is serving as president of the Carnegie Endowment for International Peace - an international affairs think tank.
Mr Burns' nomination must be confirmed by a majority vote in the US Senate. If successful, he will replace Gina Haspel, who - in 2018 - became the first woman to permanently hold the post.

House Democrats are expected to bring up a resolution asking Vice-President Pence to invoke the 25th Amendment to declare the president unfit for office.
They will seek unanimous consent for the measure. But that is unlikely to happen as most Republicans oppose it.
A full vote will then be held on Tuesday, with the measure likely to pass given the Democratic control of the House.
Meanwhile protests both for and against Mr Trump continue, and far-right groups have threatened more actions like last Wednesday's storming of the Capitol building.
Security has been tightened, and a 7ft (2m) security fence put up around the Capitol to prevent further invasions.

Trump supporters converged on Capitol Hill last Wednesday to express their anger over the certification of Joe Biden's election victory, and five people - including a police officer - died during the unrest.
Rioters were pictured vandalising congressional offices, and a laptop belonging to Nancy Pelosi - the Speaker of the House - has been reported as stolen. A number of pipe bombs were also discovered on the premises.
Among those who've been arrested are a 'QAnon Shaman' and a newly-elected West Virginia lawmaker, Derrick Evans, who filmed himself inside the Capitol.
The congressional building was stormed shortly after a rally by President Trump, where he continued to make unsubstantiated allegations of election fraud.
Mr Trump has made no public statements since he was banned from several social media platforms - including Twitter - on Friday.
