If the gun grabbers would apply the same standards to the 2nd Amendment as they do to Freedom of Speech and Right to abortions, there would be no problems.
And the ACLU's hypocrisy on this issue is blinding.
Conversely, if the NRA were to take the same approach to the 1st amendment and abortion rights as they do the 2nd amendment, then we could each say anything we liked any time we liked and abortions would be allowed up to age 18. Perhaps there is a middle road on both sides.
Lets look at the standard comparison used when looking at the 1st and the 2nd amendment. Yelling "FIRE" in a crowded theatre.
Now, that is not covered under freedom of speech, and like shooting someone, it is very dangerous. However lets look at how one would prevent somone from yelling "FIRE" in a crowded theatre, considering first that both shooting someone without cause (self defense) and yelling FIRE in a crowded theatre without cause (no fire) are both illegal.
Applying current gun control.
In order to enter a theatre run by a federally liscenced theatre owner, you have to wait outside while the usher checked your background for any felonies. In some states you would need to be registered prior to entering the theatre. In other states if the show was outside in public, you would need a Outside speaker permit (OSP). Some states only issue these to police officers and retired police officers. One state doesnt require it at all.
People could run thier own theatre, but if they let in someone who is not allowed to watch the movies, they could be found liable. Furthermore, fast talking people (auctioneers) need to have a special permit to enter the theatre, and can only do so with the permission of the local theatre security guard. They also have to pay a tax for being able to talk so fast. This all depends on the state the theatre is in.
Now in some states as well, to prevent people from talking, gags have to be worn, with the gag only removed in case of emergency.
Currently there are movements to restrict even more fast talkers from entering the theatre. People allowed would only be those known to speak less than one word per 5 seconds, and are only allowed 10 words (or 7) at a time, before having to breathe in again"
People with funny accents would also be banned from the theatre.
