How to treat a football fan

Did you have the chance to watch what happened in Colombia at the Copa Libertadores match between Junior de Barranquilla and Jaguares? A player and a staff member of Jaguares kicked a fan when he entered the football pitch, I think it's pretty annoying to have to deal with those retards but the players should not take actions like this. On the other hand, Roberto Carlos gives an autograph to a fan that also enters the pitch in the middle of a game, this time in Russia.

What do you think is a better way to treat these dumb retards? Any suggestions?
