Not everyone is in a gang (and I’ll leave the gang part out of this, because that IS racist, along with the whole inner-city bit, but that’s a separate conversation on how laws were written to specifically allow cops to target racial groups)
But anyone who is a cop is in the gang that is the police.
No, the two things are not remotely equitable. One is about a group of chosen profession, the other is an entire racial group being associated with crime. That’s an argument that’s as flimsy as a wet paper bag.
