I think in the origional comment re: someone breaking into your car in a parking lot, not only do you have the right to flash the weapon, but according to the law - it's too early to search the forums for the part I'm refering to - you have the right to use it. I believe the premis was "Threat to persons and or property".
We've asserted several times that the car has been defined as an extention of your home, did something change?
Also keep in mind that in the majority of the state, we have an open carry right.
Accidental displaying of your weapon - Well folks, it's gonna happen. Outlining under a shirt, raising your arms - thus raising the lower edge of your jacket - to get something off a shelf... yada yada yada, can and will happen.
All said and told, common sense prevails here. Can you reasonably explain to an officer, judge and or jury, your actions?
It's always good to discuss the multitude of potential situations we can possibly encounter, keep it up.
