I think that gun manufacturer and sellers should be liable for the destruction they cause. Also automatic and semi- automatic hollow point should be restricted to law enforcement agencies. A considerable tax on firearms and ammunition to pay for the medical expenses of shooting victims. Licensing all gunowners, and must carry liability insurance, and all firearms cradle to grave registration, the same as a car. But most of these incidents are so random and done by individuals with no criminal history. There is enough stigma on a psych history that these people are already deterred from seeking any kind of help voluntarily. but metal detectors everywhere, who is going to pay for that? But there should be a way to tract someone buying a large supply of ammunition especially for automatic weapons. I have issues with going through a metal detector everytime I go anywhere, why not put the burden on the gun manufacterers and owners. I don't think the second ammendment is relevant to today, when people don't usually hunt for food or need protection from wild animals. Nobody has ever stopped a shooting spree no matter how many guns are out there, because the element of surprise and target are part of the psycho's plan. Thanks for listening anyway.
Why are you spending so much time talking about automatic weapons? I will, yet again, point out that automatic weapons are neither widely available nor have they been used in any of the recent shootings. For that matter, the only major use of automatic weapons in an American mass murder that I can think of off the top of my head was the St. Valentine's Day Massacre back in the 1920's.
The 2nd Amendment was never about hunting or protection from wild animals. The 2nd Amendment was written entirely for the purpose of enabling the population to defend itself from an oppressive government. The events currently happening in Syria show that such an issue is still very relevant today.
For this reason, plans to track gun owners are a bad idea which would undercut the purpose of the amendment. What is worse is that there is absolutely no reason to believe that such a registry has any chance of preventing any of these shootings.
Likewise forcing people to carry liability insurance will only punish the innocent. The criminals will never bother to buy it, and the law abiding citizens will never actually be liable for anything. So there is absolutely no point to such a law.
Your statement that "Nobody has ever stopped a shooting spree no matter how many guns are out there" is patently and obviously false. Any number of shootings sprees have been brought to an end by guns. I think the highest number of people shot in a shooting spree was by James Huberty in the 1980's who shot something like 50 people and he was stopped when the police shot him.
There is no such thing as "automatic hollow point" or "semi-automatic hollow point." The bullet doesn't know or care about the loading or firing mechanisms of the weapon it is loaded into. It is either the right diameter and length to fit into the chamber, or it isn't.
Fortunately for the gun manufacturers and sellers, under your system they won't have to pay anything; they aren't the ones causing the destruction. That would be the people wielding the guns.
