Keep/remove M4 for Police Officers

[Haarek]

Obviously MP5 is the more realism route but lets think here, Galil vs MP5! Its pretty obvious who's going to win...
Defending your base will be 10x more easier

Indeed, but there needs to be a middle ground where the cops are reliant on the SRU. The mp5 should be sufficient enough when you are 4-5+ cops. If they need heavier weaponry they will have to call in the SRU if not already called upon.
