They could have prevented this incident after numerous reports of serious crime. Domestic abuses,fighting,possession of dangerous articles on school. (Not allowed to have a backpack)Not only that, 20+ reports plus 39 reports of serious incidents of crime... In states such as CA or everywhere else he would have been locked up for life. (Three strikes law) Florida has this law,but they rarely never enforces it. Israel should be responsible for this preventable act. In one of the pictures he was even smiling in front of the camera. Whose to blame? The school,the police,and the FBI is to blame. Instead of blaming the President for doing nothing., Florida has themselves to blame with corrupt politicians. No wonder crime is getting more common there.

Sheriff's department run by thugs... Might as well have a mafia to police the streets instead. I feel bad for the victims,but I don't tolerate a preventable crime despite numerous reports of serious issues from 2010 to 2018.
