well i see that they were in the way , as per usual
Well what did he expect? He's just parked a car outside the hotel and it's obvious what's going to happen next. If he wanted to make a quiet exit i'm sure they'd have let him out the back or something into a waiting car that didn't have any attention around it.
As you'll see in the video I linked to above, he is ducking behind someone like it's some sort of game and then pushes someone to his right who wasn't even in his way. Why not just walk out like a man and make his way to the car like a normal person? I'm sure the photographers would have wished him a good concert etc. Generally if you don't act like a prat around photographers they'll not act like prats around you.
He was looking to kick off at someone and got it.
