People are always gonna be people. They only have to make sure it isn't blatant and provable lol.
The moment one of them has to replace a vehicle cause it got blown up by a gang, they know reviving that gang could result in a net negative. If they want money, they gonna go to the people that thank them, invoice them, and ask about their day.
There's been like 30+ incidences I could've IA'ed medics on over the last 2 years. I never once did. The risk outweighs the benefits of not pissing them off.
