for Doctors, Nurses, Staff and Patients at the Hospital where he worked in the ICU, in case a gunman overcame a Security Guard and took his gun (see my earlier post that details such an instance very recently). Word travels around the Medical Community about such things...it would make perfect sense for a very fit 37 yr old man...and Nurse...to want to protect others...ergo the concealed carry permit.
I'll also repeat what I said earlier...ICU Docs and Nurses have to be "On Call" many times at any time of the Day or Night, in case of Medical Emergencies...Therefore, it's reasonable for him to constantly carry that handgun with him virtually everywhere...everyday. I'll be talking with our family ICU Doc fairly soon and get that perspective on such a scenario.
btw, re: 2 'Mags' of Ammo...should Alex Pretti be the 'Last Resort' after a Security Guard is overwhelmed...he just might need an above average amount of ammunition.
