Drunk Driver Who Killed A 20 Year Old, Forced To Wear Sign

I don't know if it will do any good in stopping other people from drinking and driving, but I'm all for anything that gives hope. Michael Giacona was ordered by a judge to wear the sign pictured above for four consecutive weekends at the exact spot he killed the 20 year old. The man was only sentenced to 90 days in jail for the crime which is a crime in itself. 90 days in jail for killing someone? I'm all for the sign thing but how about a longer jail sentence. You took a life and because you did it while drinking you get three months but if I went to a bar and killed someone I could spend 20 years in jail. How does that make sense? The first weekend that Giacona wears the sign, the mother of the victim will watch him all day. Hopefully she will get some closure, although if I was her, I think I would not want to see it because it would make sad.
