I completely agree that they knew it was wrong and should have known better, however, I hate to see a 20 year old boy’s life ruined because of stupid alcohol fueled behavior. I have a 20 something son and would be horrified if it were him in the video, but would not want his life ruined over it. Young adult/kids can do very stupid things but singing a bad, racist song should not ruin them. Murdering someone or actually committing a crime and being convicted should do more to alter their lives.
It is tragic but it's also a fact of life in these days of Google and You Tube that stupid stunts can follow a person for years if not the rest of their life. They did what they did, and unfair or not they're never going to be able to un-ring that bell.
