"How many rounds in that do you have clip? Ten? Is it a fifteen round clip?" JC said motioning towards the man's gun. "Are you sure you want to keep that gun out fed? Do you even know who's inside or what firepower they have? I'm surprised that you don't have any backup here and that makes me wonder if you even know who you are dealing with because if you did I have a feeling that you would be approaching this situation differently. It's one armed fed versus all of us. Do you really want to start a firefight here? What's the likely chance that a stray bullet might hit one of those citizens by accident?" The man said with emphasis on the last word. "This is my last warning, leave now or things will go sour." As he stood in the center of the alleyway, JC watched as the other three slowly moved towards the group. As long as they took the fed down they would be fine. Nabbing one of the girls and holding a gun against her would stop the fed in his place if his warning didn't work. It was only a matter of time. 

The fed couldn't leave. News about their gang couldn't get out or there would be trouble with the others. They made a mistake about staying.
