This is kind of an interesting video and kind of representational of modern urban life:

I think the victim made a major mistake in not attempting to call 911 immediately. I also believe the so called "security" guards were either incompetent, cowards or complicit.
I think there is a high probability that if he would have dialed 911 Mr. Toofies would have tried to stop him. At that point or when he started walking into the victim, you'd be free to escalate and that nice tat on his throat appears an almost perfect target.
What do you think?
