Just in my opinion if the photo is two years old then hopefully by now the individual in the photo has learned his lesson and has had an opportunity to reflect on his inappropriate actions. I know two years seems like a short time, but alot can happen in two years and regardless of a person's past, people are able to change their attitudes and outlook on life. So with that said, I don't think it is necessary to do the petitioning and all the ranting and the whole la dee da dee da's on this anymore. I thought it was necessary at first because I assumed the photo was taken at a recent baseball game, I didn't think it was from two years ago.
If it was two years ago then my comment is that people make mistakes, some mistakes may appear to be worst than others, but that individual needs to learn from the two year old mistake and move on.
Personally, I don't think anyone would want someone else to dig up some expired trash on them from two years ago then display it on a social website and do a petition with different commentaries. We probably wouldn't have come across this during our year/years teaching in Korea if it wasn't dug up. Well, I know I wouldn't have. If the man was going to face any consequences for his actions then this should have probably been done at the time of the actual incident two years ago, but unfortunately no action was taken, so this is one of those second chances that people get in life to learn from a history and move on and not to repeat that history because next time it could lead to serious consequences especially if he did this back home.
Anyways, at least from this discussion we understand that such actions are not in the least supported so for those feeling quite adventurous on a night out, think twice before doing something inappropriate.
