1. Hersch didn't get emotional, he just flash a lil black man rage to get the cac to back the fuck off. No need to get physical because Kid would be charge with that shit. You got to assume he done heard it all before and knows how to deal with ignorant ass people who confront Kid.
2. It was a sucker punch. anybody can get it, that's why its called sucker punch. If you know you can beat the shit out of someone, why bother to go there when you know they don't want it. That's what he did and said to kid, the first one is free but he really wasn't tripping about that.
3. The client gonna and will have free range and its hard to keep track of someone who violates their own protocols. If your employers says to give him the room and after you walk out, slips out another door, what can you really do about that? You get paid to follow instructions, not to violate your clients prerogative's.
4. As far as the gun scene.. shit can happen after all bodyguard are paid to take a bullet or get an ass whooping if need be.
5. Hersch never threatened. He just said, shit if you gonna pay $$ to a mofo, break me off, you know I'm good for it and have earned it many times over. Kids wasn't tripping about the money. It was lint money to him, so he didn't care either way. Mentally, he was in a different space. Hersch didn't threaten but simply appealed to the common sense resolution to a problem, Kid with the help of his brother created.
