sucks this guy was un-informed of the requirements we are supposed to follow.
I had a similar situation driving to the airport at about 4:30 am. pulled out by adams county sherrif (where my permit is issued), I am in uniform(pilot). I was speeding, no denying it. He asked for my drivers license etc. I wasn't carrying since I was going to work. he gets on his loud speaker..."
Mr Sniper7 are you carrying a firearm?" I shake my head no, he comes back in a big huff and proceeds to chew me out for not telling him.

just another example of them not being informed. I understand from their point of view that they would like to know...but they aren't going to know when a real bad guy is armed and he certainly isn't going to tell them.

the only good thing about telling them is it puts them at ease, and usually saves you a ticket. After that I decided I will tell them about it no matter what. It is a nice common courtesy.
