to be disgusted by Diamond League contestant's violence?

[MamaMotherMummy]

Richard Kilty in the second heat of the men's 100m competing against Usain Bolt, was disqualified for starting too early.

Argued the decision with lots of ghetto arm action then pushed one of the workers that was trying to usher him away (an elderly man). What a thug. I am so shocked and I think he should be prevented from competing in other competitions. Violence towards officials should NOT be tolerated.

I think you know what I mean by ghetto arm action.

I've no idea what 'ghetto arm action' is either

I can't find anything about this on the BBC web site - interesting as the Beeb seem to be covering the event.
Yes, this guy is going to regret his actions for a very long time.
