this is just an idea, maybe make a SWAT medic who can heal, but be part of the SWAT team and if he drops his bag, be able to use a handgun and arrest. Just an idea. Also, maybe think about this http://www.code2high.com/variouspd.htm it's used, I've been informed by some sites, that it is used to decontaminate cadavers. It would make sense because in the gas mission, there are like 10 bodies that need to be decontaminated, just a thought.
