bring out the guns honestly..if they pull theirs then you know what to do(shoot)..if not then you do as stated above call the cops to head out.make sure you say something to the effect of them having weapons or something that would throw a red flag so to speak cause if you say we have some guys sitting here giving us a hard time..they wont respond emergency..they cops could care less about a lot of domestic type stuff..but if you act as if shit is about to hit the fan..then they will come barrelin through
