Tripower 455 - You are right, in everything you said.
For those who don't feel they have the skill, experience, training, judgement required YOU WILL NOT BE OBLIGATED TO CARRY A FIREARM!
If this is actually enacted (I doub't it unfortunately) it will be an option to carry or not to carry. The bad guys then know they run the risk of running into Tripower 455 or Flying Guy when they bash in the cockpit door. Bashers will be greeted with a face full of pistol. I WILL immediately pull the trigger. Not too tough a snap decision for me.
