As a responsible gun owner, I find this immature and selfish.
This would, IMHO, bring unwanted attention to we who OC. The LEO's would take more time administering harassment to those of us who exercise our rights.
I understand the question, I just don't see the result as being positive.
If the popo come to a MWAG call and a badge is produced, it's game over immediately, then the LEO's start looking for someone to blame for the call..... ;(
again...just my PO.
