Some athletes are good at what they are do but it doesn't mean that they have the mentality to handle the pressure, I understand how things like it happen because it happened to me.  I wasn't on the Olympic stage but it was national that lead lead to my down fall.  I was treated specail and I felt like everything was about me and I was the bigger then the sport.  My senior year in high school I snapped, Knocked down a ref giving him a serious concussion, then left the gym head butting the door knocking into a trophy case.  A lot of people have had thoughts of when they feel they are screwed that they want to attack people and instead of self-control it's acted upon.  I paid for what I did, I had to make a public appology and then had 50 hours of community service to complete. If you believe in Karma, my knee blew out, I lost my scholarship to D1 schools and some other issues.

It's easy for people to say, I would never do that because most people never make it to that level,  I was one that once said something similar after watching a guy from my school district throw down a silver medal at Sidnye games. But I was wrong. 

OG,  so when I said "I  can see how it happened" it was more from personal experince.  I hope that explains my comment.

It's just hard for me to fathom I guess it's a matter of walking that mile in another man's shoes.  It doesn't make it good, it doesn't even make it acceptable but since you've walked that mile I appreciate you explaining how something like this might happen.
