No chance of him joining some police agency and and using his power of being in law enforcement to do whatever he wants to or whatever he is told to do to the citizens like you or me or someone else?
Not any more a chance than you or anyone else. Did the pilots who bombed Germany & Japan come home and blow up buildings? How about the ones who shot Germans? Did the soldiers come home and kill Germans? Of course not. BTW some of the most abrasive and arrogant officers you'll ever want to deal with are animal control officers. Not saying they don't get some leglit calls but rather this.
We live in a nation and society that gives more protections to animals than kids when it comes to abuse. If you don't believe it go take Foster Parenting Classes and find out for yourself. Their goal and agenda in many cases is reunification with the perp parent yes even in sexual cases. Now is that sick enough? Kinda makes a fake puppy kill movie seem trivial.
