If Chaos confirmed that he actually was a cop, that’s good enough for me but if his online persona is any indication, then he was a cop that didn’t take his oath seriously and was probably a dirty cop
There are a lot of agencies all across the country. The standards vary greatly.
If I remember Agnostic was a cop in the south. Typically the lowest standards for hiring. Ive known guys who held command positions, lieutenant, captain, commander... in smaller po-dunk towns that couldn't even get hired as an entry level officer in Portland. And Portlands standards have dropped substantially since 2020.
I don't think he was a dirty cop but probably not a good cop nonetheless. Id also imagine that his political views are shaped by a bitterness about his former profession.
