You can have a gun and get shot before it you get to shoot it. But it still doesn't matter, doesn't give him license to shoot in a crowd. They trying to get Troy Ave to snitch, that's it.
Yea very true, you can get shot before bringing yours out but if there isn't any video or proof of this, a jury seeing a black male who is also a rapper who raps about shooting people and other wild shyt, will think Troy either had the gun on him (which doesn't make sense, but a jury doesn't care) or will say he went outside to retrieve one.
plus, once you leave the area of an altercation, you can't come back around and claim "self-defense" the D.A. will eat your ass for lunch on the stand and ask "If you feared for your life, why did you re-enter the establishment seemingly in pursuit of the individual(s) you claimed put your life in danger?"
