I think people are confusing a possibly slight over reaction to a real threat by the FBI vs. violently policing Black communities as standard procedure. Just this week, we had video of a Black family being pulled out of their car and handcuffed for no reason.
So perhaps this raid was a bit over the top, but the investigation seems on the up and up, and being cautious when high caliber guns are known to be involved…
