The cop might have used a lethal AR if he had one. You dont get the option until corporal to have a lethal option and even then there are policies restricting when it can be used
That is funny that you say rules go the cops way.. Hell the fact that anyone hearing the siren can start shooting at cops when they know the siren has nothing to do with them disproves that..
To be honest rotor should not be allowed at al.. after all how is a chopper supposed to be able to disable another like that without taking damage.. it is exploiting arma coding imo
I believe this rule was more for the case of the guys who lock themselves in a house or attack on top of a roof where we cannot get to them without a corporal+, not for the fed as you say here
