The fan got all the way to Federer and tried to get him to wear a Barcelona hat, actually putting his hands on Federer's head. The fan was close to Federer for about 5 seconds before he ran from security and eventually got tackled and carried off. Scary how easily this fan was able to reach Federer and how long it took security to react.
The Security seemed competent enough ... I think they may have spent a little too much time wishing they weren't going to have to wrestle with a douche before they got around to getting on with it, but, on the plus side, they didn't get sucked into a wild goose chase where the baddie goes back around and gets to the principal a SECOND time with no Security around to protect him 'cuz they all chased after him. I'd call it a pretty solid performance based on the video attached to the story.
