I've refrained from commenting, as although I am an EMT, I do not work as one regularly.
DaveB; Before you get your panties all up in a bunch, consider this:
Long standing doctrine of battlefield casualty care is to disarm any patient with an even slightly altered mental status. This is part of your AVPU assessment, just after considering spinal immobilization (that is for gsd), in other words: one of the first things you do. A "A slightly altered mental status" can and does include, unconsciousness, not knowing where you are or what happened, panicking, inability to stand....... in other words: almost EVERY casualty worth any real attention.
This is a matter of safety and security of the unit, the care provider, and the individual. People who just suffered blast or ballistic trauma rarely behave rationally, often become hostile towards anyone and everyone, and in some cases become suicidal. Disarming them includes taking away all weapons and ordnance. Medical Evacuation units will not accept casualties that are still armed with so much as a smoke canister.
Casualties are disarmed in combat, often while under fire. I think you can tolerate being disarmed because an emergency care provider does not know you, does not have a complete knowledge of your previous or current mental state, and is responsible not only for his own safety, but, in part, the safety of all of the responding personnel.
