MAYBE The cop and the man who (apparently) died did not like each other , Had problems at the club and the cop got even …
OR .. They planned this together for $$$ .. EMP at the scene may have been part of the play ..
Certainly the Whole story stinks .. Kneeling for 8 minutes on the man .. 8 minutes is a long time .. WEIRD … To many things don't make sense .. I hope Anons can tie it together and have solid facts
