I have no idea what others feel inside when they carry a weapon in public, but I was taught gun safety as a child and many years ago took a glass that allowed me to carry a concealed weapon and it was less about feeling a new power than it made me think all the time about the responsibility I had.
I have not changed over the years and still find that being armed is a hell of a responsibility and and I constantly think about that and how I will react in a situation like took place in Arizona a couple of months ago, when Congresswoman Gifford was shoot buy a nut. I know this you don't want to be the bad guy if I am in range.
I will also tell everyone that if you use you weapon to stop such an event when you are done put your weapon on the floor and step back to avoid being shot yourself by the police or security because they sometimes get excited, and they don't know who the bad guy was.
When they do show up do what they tell you and careful not to make any movement that can look like you are going to pickup your gun.
