evidence: While many facts remain to be sorted out about how hundreds of rioters caught police off guard and stormed the nation's Capitol building last month, African American studies professor Mark Anthony Neal said recent history shows that had the multitude of marauders been Black Lives Matter protesters the law enforcement response would have been very different. [...] Critics contend the stark contrast between the massive law enforcement response to recent BLM protests in Washington, D.C., and its weak performance during the Capitol riots is evidence of the double standard they allege can be found not just in the nation's capital but in police agencies across the country. [...] "No one can tell me that if it had been a group of Black Lives Matter protesting yesterday, they wouldn't have been treated very, very differently from the mob of thugs that stormed the Capitol," President Joe Biden said during a Jan. 7 press conference, adding that one of his granddaughters had emailed him a photo of hundreds of National Guard protecting the Lincoln Memorial during a BLM protest in June.
