Maybe they want to stay alive. They depend on their brothers in blue to help them when things go south. Nobody likes a snitch, and that goes for pretty much any organized group. You want them to be perfect angels 24/7 while they risk their lives every single day. SMDH.
I think you posted that to the wrong person, but that thing about nobody likes good people who will take on the bad guys aka “nobody likes a snitch” is some modern wacko ghetto thing that emerged from the left pushing black culture onto America, it is not what made America great, real Americans stand tall and take on the criminals.
