Flipping out after a match could mean criminal charges for David Nalbandian
He kicked an advertising banner, which ended up smashing into a line judge's shin, causing him to bleed all over the place.
Naturally, he was kicked out of the match after that.
Now, Nalbandian might be facing assault charges, after the official filed a complaint.
Unfortunately for Nalbandian, he doesn't have much plausible deniability, since the whole world can watch his tantrum on video, right here:
Despite all that, I think it's clear that Nalbandian didn't intentionally hurt the line judge.
Yes, it was stupid, and yes, he should have known that by kicking that particular banner, he might knock it into the judge. That's just common sense. However, I think it will be hard to determine that he was actually trying to hurt someone. Then again, criminal stupidity might be a crime in England.
