If we arm firefighters and paramedics who will be responsible for patient care? When a Deputy Sherrif is disarmed and shot in the leg in an emergency room - a man whose only job is to keep the prisoner under guard and everybody else safe – how can we expect firefighters and EMT's to do thier job while keeping their sidearms under control. There is no sense in securing our weapon, things happen fast in the real world, and the point of being armed is to have the ability to protect yourself quickly. Having the weapon readily available is imperritive, you cannot say to the person attacking you to "hold on, buddy, I have to get my gun." If you have time to get your gun from where it is secured, the purpose of having the weapon is corrupted.
If you have time to arm yourself before entering a hostile scene, you have lost sight of your responsibilities, and if you arm yourself after a violent incident you have become a vigilante. I am not a commando, or a Guardian Angel. I am a firefighter/EMT, and I have a job to do, and every last piece of gear that it takes to do that job does not bear a fraction of the weight of a sidearm.
