school administrators REALLY need to care!!!

another shooting right in the wake of parkland! Has anyone noticed that it's only after another shooting that politicians say we need gun control and then they don't do anything. Aurora, Sandy Hook, Parkland. Donald Trump said he wanted to supply teachers with weapons to defend students. As the Parkland students pointed out we NEED BETTER background checks and SCHOOL ADMINISTRATORS to CARE ENOUGH TO RECOGNIZE signs of violence to DO SOMETHING TO INTERVENE! We never saw school shootings like this in the 80's so why in the mid 2010's?
