In a desperate bid to save his reelection chances, Trump is sending his goons to escalate tensions in dozens of cities across the US. He is ignoring pleas from the mayors of those cities to refrain from doing so.
This is sowing anger and discord. Some people have reacted with violence. This, unfortunately, plays right into Trump's hands. It reinforces the conservative narrative that all Black people are violent and they really don't deserve civil rights.
Violence. Anger. Division. Conflict. It's what all fascist dictators want, and what Trump craves. That despicable bully.
(And of course, our resident Trumptards are cheering him on.)
