.  The problem at Parkland was not the cops outside, it was the factors that led to Cruz having both the inclination and the ability to perpetrate the carnage.  The claim that citizens need unfettered access to firearms to protect themselves against tyrannical government is just bull sh!t that ignores the fact that there are many functional democracies around the world that are stable and require citizens to has licenses to own firearms, the licensing process working to keep such weapons out of the hands of unstable people like Cruz, but allows those of more stable character to own such weapons.  No self-respecting man with a gun would have stood outside the school like a little coward while kids were being murdered inside.
