Boston Celtics legend Bill Russell has had enough of sitting United States President Donald Trump.

The entire world is watching a scary and and scene play out in Washington, D.C. on Wednesday. Supporters of President Donald Trump stormed the U.S. Capitol during the Senate's debate on the certification of President-elect Joe Biden.

After engaging with Capitol Police outside the building, the rioters broke into the building and made their way inside the Senate chamber and offices of elected officials.

The ugly scenes are drawing reactions from persons both foreign and domestic, including those in the sporting world.

Boston Celtics legend and civil rights activist Bill Russell chastised Trump for not taking action, citing the double standard with respect to how the President has deployed forces against Black and Brown people:

“How long would it take to deploy the National Guard if they were black & how many would be dead?” Celtics legend Bill Russell tweeted Wednesday. “This is NOT#America! A sitting #President did this @realDonaldTrump #Coward & yes that is a #Confederate flag outside the Senate chamber. How did they not know this would happen?”

Numerous commentators, reporters and athletes cited the same double standard as Russell.

Former NBA All-Star Dwyane Wade issued a similar statement, and Cleveland Cavaliers forward cited the events as a “blatant example of inequity in how law enforcement chooses to deal with those involved.”

Indeed, another video of police taking selfies with some people making their way into the building has created more outrage.

For his part, President Donald Trump sent out tweets decrying the violence, though he initially refused to send the National Guard.

One thing is abundantly clear: Wednesday, Jan. 6 will go down as one of the more dire days in the history of the United States. It doesn't take a tweet from Bill Russell to realize that.
