Everyones job is nothing more than making money. Akon is makin money where ever he goes. If they didn't like his music, they didn't have to be there.
The kid/guy deserved whatever he got. Everyone has thier own opinion on what they would do in that situation, you all proved that.
Personally I would've had security escort him backstage.
One thing did seem kind of odd though. That guy/kid didn't seem to be putting up much of a fight...
