Are there good cops? Yes just like there are bad ones. Bottom line is there will always be law enforcement.
The problem really falls on society for not demanding reform and accountability. We've become so self centered and our attitude is as long as it doesn't affect me it doesn't matter.
Police in and of their self aren't our problem it's authority as a whole. Government is corrupt at the top, and it's always been from the beginning because people desire power, prestige, etc..., and it trickles down.
The masses need to raise up in unison and demand accountability but this seems far fetched because sadly we can't even agree if Ronnie is better then Dorian.
