space based weapons have existed for a long time.....and you're worried about someone bringing a gun into space? Lightweight composites used to form space stations and spacecraft are vulnerable to scratches - and you're worried about someone bringing a gun? A broken mercury thermometer could do more damage.
So anybody with a working brain doesn't need a gun to do really bad things. Pretty smart. Referencing the first amendment sure makes it sound stupid to anybody scrolling past quickly, but that was just super-smart troll bait that worked perfectly!
