Body camera shows as deputies were attempting to escort 82-year-old Anthony Goulding’s wife out of the home, Goulding began pouring gasoline on the carpet outside of a back bedroom.
Goulding’s right arm catches fire and then he throws a gas canister at the deputy. The flames grow larger.
Goulding passed away in the house fire, along with a dog.
In reality the majority of what cops engage in day to day is bad, but let's say that the majority of what they do is good for the sake of argument. Let's even use your examples of 99% good vs 1% bad.
You don't get a permissive license to do bad things based on your good doings. You can't donate to charity and then rob a person and say "yeah that's even, so all is good". You aren't allowed to do bad things even if you're ordered to. There is a difference between being ordered and being forced, e.g if you're kidnapped, bomb strapped to chest and told you're going to explode if you don't rob a bank. That's different than actively choosing to go into a profession where you know you'll have to evict people, protect capital interests, harass and disproportionately jail minorities, etc. and "not liking it" but being ordered to do it on the job.
So even in this made-up fantasy world where 99% of what cops do is good, they're still bastards and shouldn't be doing the evil shit they do.
