I think it is quite a few.Yet another glaring example of how things work for these guys. I genuinely wonder how many cops pursue a career in policing just so they can engage in criminal activity without concern for consequences. It's just way too common at his point. I definitely don't think all cops are bad but a significant percentage are.
I also think that the culture is such that those who don't want to go along with the "We, as cops, are the best criminal gang" (or, alternatively, "we are the occupying force that needs to keep the unruly natives in line and the idiot civilians don't understand and can't be trusted") attitude are pushed out over time.
