You can speak freely, but that doesn't mean you can scream FIRE in a theater without consequences,
oohh no he di'int.:banghead:
But we ARE still allowed to walk into a theatre without having our vocal cords removed aren't we. If there was a fire we would be lawfully able to yell "fire" wouldn't we. That analogy doesn't hold true for guns.
In many states you MAY NOT leave your home without your gun stowed away and locked up making it perfectly useless in case of a fire.
