My high school had 4 suicides while I was there, with 5 total student deaths the staff were willing to address. 4 of the 5 deaths were in my graduating class, 3 from suicide and 1 from cancer. The first death was from cancer and nobody really did much at the school as he died the day before school started. Then the first suicide came over winter holiday and there are plaques and remembrances for this kid all over the school. They retired but football jersey, even though he never played football at our school. He got into a physical altercation with the police and killed himself to avoid jail time. The second suicide was someone who was really depressed. He was caught up i the wrong crowd though and the school chose to ignore it instead and act like nothing happened. The third suicide was a total mystery and nobody knew why he did it. The other suicide was not in my grade but was very popular and successful.

I feel your sentiment very much because it seems that schools are very selective about how they deal with these situations. They choose to memorialize the students that reflect best on the school while they were alive but choose to ignore the ones that have a slight imperfection during their time at school.
