Now, some "in house" computer systems (the computer program being used by departments for their own info including dispatch, email, and cases, etc) can run inquires into the stat'es system, and can cross-reference the "in house", so when you run a person, you can get license, warrant, and any previous contact that dept has had with that individual, and these software programs can be set to "flag" people, and firearm licenses is one of the alerts that can pop up. So that requires a LOT of things to be set up JUST right, and will only flag people that were licensed by the inquiring agency, or had previous contact.
So, for all intensive purposes, No, they wont know.

Personaly, if the firearm is on me, I notify. Worse come to worse, I'de rather be pulled out and disarmed (which has never) than not tell and end up looking down the business end of a G-Lock of a very nervous rookie who saw the grip when I got my wallet.... We all know those G-Locks are accident-prone
GOAL, NRA, and GLOCK stickers will be a hint though

I think that would be a good idea in any case. Of course it really isnt the LICENSED people you probably need to worry about.
