evidence: Black Lives Matter protesters in Washington, DC, last summer found themselves facing a massive show of force: military helicopters hovering over the city, National Guard troops patrolling the streets and tear gas filling the air. [...] DC police arrested more than five times as many people at the height of the Black Lives Matter protests last summer than they did during the day of insurrection at the Capitol, according to a CNN analysis of Metropolitan Police Department (MPD) data. And many of those arrested amid this week’s unrest were detained on less serious charges. [...] President-elect Joe Biden focused on the racial disparities in a speech Thursday, saying "no one can tell me that if that had been a group of Black Lives Matter protesting yesterday, they wouldn’t have been treated very, very differently than the mob of thugs that stormed the Capitol."
