Up until some point in the 60s or 70s you could carry concealed on a plane. And before 9/11, unreasonable searches at the airports were less likely. Also, no a state cannot make a law that overrides the Constitution. Shall not be infringed means shall not be infringed. It doesn't matter "what type of gun." That's an admission of lost freedom right there.
I would still like to know at what point you would say "Hey, that's a lost freedom." Could you tell me that?
When exactly were the conceal/carry laws changed for airplanes? As far as unreasonable, that depends. Again, if you have nothing to hide, why is it a violation of your freedom to promote safety? If 9-11 hadn't happened, and an airport worker asked to search your bag, would you let them? How would you propose, in light of 9-11, that security be done at airports?
I guess I'm of the mind that *IF* I felt I had lost a freedom, I'd do my damn hardest to get those freedoms back. I guess working in corporate life has made me a 'if you present a problem, present a solution' kinda gal.
