I can do a google search and find at least three "school stabbing sprees" in the US on the first page. In fact, it seems like you're much more likely to be stabbed while going to school than shot.

Sharks kill, on average, about as many people as school spree shooters per year. Those deaths to sharks are preventable by offing all the sharks, are we doing that?

Making policies based on outrage is a losing proposition.
