Probably not. I was recently at a jeweler that was one of the few retailers in our are that carries Omega watches, and they had a big sign up front declaring it a gun free zone, which I promptly ignored. The "security guard" on site was unarmed unless, like me he completely ignores such unconstitutional signage.
You are exactly right. There are all kinds of dangers that come with living in a free country. We've got car jackings and burglaries, etc, but now we have had a dramatic increase in murders and rapes by illegal scumbags who are not being kept locked up. They are being but let loose instead of being deported or sent off to prison... i.e. Kate Steinle and the elderly woman who was raped then murdered. I should have gotten my carry permit long ago but I keep putting it off.
