I have read and heard many different ideas regarding gun control. Each time someone suggests an idea, another person has a counter to it that dismantles that idea.
As it stands now, there are so many guns in the U.S. that I seriously doubt that any idea is 100% workable. We can do all the psychological testing, have longer waiting periods and even do picture/fingerprinting ID’s and it will all be in vain. Guns are out there and they are readily available for purchasing. Even getting the AR’s, Uzi’s and other assault style weapons off the street won’t stop mass or serial killings.
