In my opinion bouncers are there to prevent this kicking off in the first place. If people didn't fear this being the outcome there would just be endless trouble. Same with with the police, they should be permitted to give people a good kicking on the same basis. Sure the police should be seen as fair and approachable. But I can't help but feel a lot of situations would be avoidable if they were feared by those who think they can get away with petty things like this. A presence should be enough and that's no longer the case in many situations it seems.
Does the fact he’s a bouncer confer on him extra rights/allow him a greater scope for leniency?
First punch definitely. Maybe not the rest. A push would probably have sufficed.
