Jardine is lucky if you ask me. If that guard was feeling ambitious he could have pressed charges and had Jardine thrown in jail. It may look minuscule but its still considered assault.
Its one of those things where you have to keep your temper in check otherwise it can bite you in the ass.
According to Keith's camp the guard grabbed him first so I doubt the cops would do anything at all if they were called, especially given there were no injuries and the situation was already defused. Guard would just look like a ***** in front of the entire live audience.
Everybody good, plenty of slaves for my robot colony?
