Yeah I have sort have learned from life experience, if the guys with guns are not in uniforms of Law Enforcement or Military(US or Canadian) I am going the opposite direction in a pretty big hurry.. The odds of the random guy with a gun being a good guy - not all that good in my experience.
Uniformed military (US) are very rarely allowed to carry weapons off base. About the only time you will see them is if they are traveling as a unit to a field exercise at a nearby base and they make a pit stop at a gas station. 90% of the time, they are required to hand their weapon off before going inside. In the rare event that the CO authorizes them to keep their weapons slung, it will ALWAYS be unloaded.
A big problem with these gun activists is that open carrying a rifle is going to do nothing for self defense even though they claim thats why they are carrying them. A long gun strapped to your back is going to be very hard to bring to bear in closed quarters such as the lego aisle. Also even if they go to the range to learn to shoot most people do not have the training to safely and accurately use a gun in a self defense situation. So even if they are able to bring their gun to the ready, the chances of them being able to hit their target among other panicked guests and TMs is very small.
Pretty much this. Most gun hobbyists I've known like to practice
military airsoft shooting techniques which have 0 application in the civilian world. Things like suppressive fire don't work when it's 1-2 targets with a dozen innocent bystanders nearby .
Generally, open carrying a weapon makes you the first target if a criminal is going to rob/shoot up the place. Most criminals will scout the area first before carrying out their plan (after all you don't want to rob one register only to find out there's a uniform cop in the lane behind you). When someone is obviously armed, the criminal is more likely to just shoot him in the back of the head and eliminate that threat immediately.
Case in point: In 2011, 72 cops were murdered on duty, the majority of which by firearms. Only 17 of them were able to shoot back. (
