I personally would not be in favor of creating background check laws for personal sales or sales at a gun show. I have never been charged or convicted of a felony, I have never been diagnosed with a mental illness nor charged with domestic violence. I have a license to practice medicine, a DEA license to prescribe medicine and a concealed carry permit and a valid passport. Yet I am "delayed" every time I attempt to purchase a firearm. I have never been "denied" purchase of a firearm, they simply make me wait 3 days to pick it up. Every single time, regardless of gun type. Is there are a lot of criminals purchasing Benelli Super Black Eagles? I am sure there are lots of sales of Browning stainless stalkers in 325wsm to gangbangers and drug dealers right? I do not own nor ever purchased and AR type of weapon, so surely I should not be on some type of secret government data base that monitors such things? I have had friends who are police officers run a background check on me and they come up with nothing.
This is no real big deal when puchasing a brand new gun, I don't "need" the firearm right that minute. But changing the law to make me have a background check for every private purchase or purchase/trade at a gun show would essentially put me at a point where a private sale or a gun show is essentially a complete waste of the sellers time. I am not in favor of making it more difficult for responsible people to obtain firearms.
Now many of you would probably ask, really, if changing this law saved even one life, wouldn't you be willing to give up the ability to have a private gun sale or go buy something at the gun show? Yes, I would, but me giving this up truly does not answer to the greatest question and the answer to what is truly the problem. There needs to be active attempts to diagnose and treat/commit people who are prone to commit these crimes of mass murder. Let's all be honest, the guy could have chosen many other ways in which to have achieved even more deaths, we all know it, yet we continue to blame the gun, the completely inanimate object, while very unfortunately many people suffering from mental illness and are quite capable of being the next headline are roaming our streets.
Put my tax money into safer schools, and better treatment and diagnosis/commitment of mental illness. Not into making it more difficult for law abiding citizens who have been background checked to death to buy firearms. End of rant.
