They will not learn because they refuse to.
The missing lessons from Pulse:
You are on your own.
You are your own first responder.
Depend on Law Enforcement and accept it will fail you.
No laws will stop crazy.
Gun Free Zones are hunting preserves for the murderous insane.
Omar Mateen began his killing and maiming rampage at 2:02 am. Police began to arrive at 2:04 am. He was sent to Allah at 5:14 am after killing 49 people and wounding 58 more. It was a catastrophic failure of Law Enforcement which was to be repeated at Robb Elementary School in Uvalde six years later.
I am tired of petty stupid people playing politics with the lives of others. Even more tired of those who eat that suicidal pablum and ignore the obvious remedies to have a fighting chance to stay alive.
And it is a fighting chance, not a passive chance.
Prepare accordingly.
It is also worth pointing out that the Pulse massacre was the defining moment that brought about the creation by Erin Palette of Operation Blazing Sword. And that served to demonstrate that there are a great many gun owners, and gun instructors, eager to support the right of all Americans, including queer ones, to defend themselves with suitable tools.
Arm yourself. Which means prepare your mind for reality. Discern the area you occupy. Pay attention to others. Dont assume its all sheeple and rainbows. Teach your mind the smooth transition from relaxed alert to "ere now, wots dis?" Go learn a combative where you hit and get hit. Make it all pleasant and even fun. When the stuff hits the fan, act. Survive.
