The forcefields are malfunctioning. The "Gun Free Zone" forcefield that is.
Here's a first hand account of the Florida School Board shooting from board member Ginger Littleton.
I was concerned about my guys. They were lined up like ducks in a row. He was already basically standing on the same level as them. I knew something bad was going to happen. That was my only option. ... My guys had three-ring binders and pencils for protection, and that's all."
Once again we see the fallacy of "Gun Free Zones." They simply aren't. Laws and signs prohibiting guns didn't keep a man from walking in armed and threatening the lives of everyone in that room. Littleton paints an all too familiar picture. Helpless, disarmed victims at the mercy of their assailant. Littleton jumped into action with the only "weapon" she had. Her purse. She failed, and the only reason she didn't die is because the shooter didn't intend to kill her.
Make no mistake about it. This is the world anti-gunners want for all Americans, as described by Bill Husfelt,
"The only thing we had, the only thing we could possibly do, was buy time. ... He had us. He could have sat there and picked us off."
Let that last sentence sink in. "He could have sat there and picked us off." Gun control provided them with absolutely NO real security, only the illusion of security, which was shattered the moment Duke walked in.
There are only two reasons everyone in that room isn't dead right now. One, Duke didn't walk in and execute them all. Two, a man with a gun shot him, stopping the assault and forcing Duke to end his own life.
H/T to WizardPC, who succinctly notes how this played out. If it sounds familiar that's because this is the basic progression of every "gun free zone" shooting. Those who create these victim-rich environments should be held responsible.
