In the 80s the DC mayor was a drug dealer. You have way too much faith in DCPD.
I don't doubt DCPD is corrupted. I just can't imagine any street-cop, on his own and even if the biggest marxist in the world, getting involved in J6. Its not their game
I CAN imagine it, if that so-called DCPD is actually an agent/reports to some other agency in Fed.gov
