Dirty Pool

I showed my students a video similar to the one above about the hockey dad who shined the laser into the eyes of the goalie of the team his daughter was playing against.  Sadly, I knew this was coming: what's the big deal? I don't see what he did wrong; I had a laser flashed in my eyes--it didn't hurt.

I guess these responses would make me even sadder if I didn't know they were coming...
