Always half fake and full fake news that people believe. Most ‘mass murders’ in the USA are gang bangers killing each other…who were released from jail because some feel good politician or judge heard the pink say he’s sorry and won’t do it again. And then he does.
Actually according to the FBI Stats 54.3 % of people murdered are killed by people who knew each other and a large percentage of those are women killed by their boyfriends or husbands. That is exactly why Red Flag laws were passed in many States.
And if we look at your statement about criminals who were imprisoned for murder that is what I would call "after the fact" which simply means that putting the murderers in prison does not bring the dead back to life.
Rather preventing criminals from getting guns in the first place would have saved the majority of those that were murdered. Only severe and thorough vetting before the purchase of a weapon along with registration has proven effective in keeping criminals from getting guns.
Here is a "German incident" from last year about how gun control often works more of the time than it fails. A Nut Case was refused purchase of a handgun and rifle but he attempted to make his own. He attacked a Jewish Synagogue and the people saw him coming with the home made pistol in his hand. The nut case shot the gun but it misfired as his home made zip gun was not of the best quality. The German Police were on the scene in minutes and nabbed him. Again vetting prevented this nut from getting a lot of firepower that could have resulted in him wiping out the entire church crowd in seconds much as Dillan Roof did in the U.S. several years ago. He was a nutcase that should never have been permitted to own a weapon.
No system is perfect but to have "no system" as we currently have at the Federal Level is pure insanity as once a newly purchased gun is re-sold in most states it becomes lost to vetting and many find their way into the hands of criminals and psycho's.
As a matter of fact Law Enforcement has found that there is an "Iron Highway" of unregistered weapons that is in constant flow from Southern States with lax gun laws into Northern Big Cities that have tough laws which renders their gun control totally useless. Again pure insanity.
About 2 years ago in London (The London Bridge Incident) a group of nutcases wanted to commit mass murder but the British Vetting System flagged them and refused them even the purchase of a shotgun. The Nut Cases then attacked a bar full of people with knives and the bar patrons then attacked the Nut Cases with broken beer bottles and chairs and beat the "H" out of them. Again the British Vetting system worked and worked well.
As one can see gun control does work more of the time than it fails but people do not want to be inconvenienced with paperwork and they think "It will never happen to me anyway" so why should I support gun laws. Famous last words.
People will then scream that registration leads to confiscation but they ignore the fact that Europe is still awash in guns and you can still buy guns in Australia, New Zealand, Japan, Korea, Thailand and the list is endless. I had a buddy who had a penpal female in Thailand (if I remember correctly the Asian country) and he and I were both shocked out of our shoes when she sent him pictures of her "brand new" machine guns she purchased and yes they were registered. Now even we Americans are not allowed to buy brand new machine guns but they are and again they are all registered and quite legal.
I think too that people who go paranoid over registration fail to realize that the U.S. could outlaw a certain class of weapons even without registration because once a certain type of weapon is outlawed you could never use it in self defense, never take it to a public range to shoot it or take the risk of selling it and then getting caught and going to prison. In short a newly prohibited weapon owned by a law abiding citizen becomes totally useless to him even if it was before never registered.
