Again, anyone with the money and connections can get their hands on any weapon they want, there's nothing to stop them from doing so. Criminals have used body armor in the past ( Los Angeles California ). Killers will kill, regardless of gun regulations, laws, legislation, or restrictions. Also, check your history concerning machine guns ( 1920s and 1930s ).

Like I said, nothing is going to stop killing, gun violence, or mass shootings. But our regulations can help decrease the body count. And limit access to weapons that can inflict massive amounts of death in short periods of time.
Here is a real example. The Orlando shooter went to a gun store to buy more weapons and body armor. They thankfully didn't sell to him. Let's say we do things your way and drop gun control regulations, and he goes in there and buys body armor and a machine gun. Do you really think the body count would have been only 50?
Speculation, at best. No one knows for sure what might have happened under different circumstances. We have no way of knowing how many he would've killed before the cops killed him. The point is, many died, and there's absolutely nothing that would've stopped him from killing many people.
It's not the number of deaths, but gun violence in general, whether it's 3 or 4, or dozens at a time. The point is, and I repeat myself here, there is no way humanly possible to end gun violence. We do not have the technology to read minds. We don't know if the grocery store clerk is on the edge of sanity or not. We don't know if our next door neighbor is depressed, angry, and ready to end it all, and take several innocent people with him when he goes. We don't know if our mail carrier is going through a nasty divorce and wants to just end his life, and take several innocent people with him/her. We never know who is going to go postal, when, why, nor how. We can't read minds. We can't test everyone for mental illnesses every few months forever. We can't stop suicides, murder, illegal drugs, wars, depression, hatred, nor any other human emotions or behavior if we don't know in advance.
Think about domestic disputes, vengeance, hatred, racism, fanatics, terrorists, lunatics, crazies, suicidal people, the mentally disturbed, alcoholics, drug addicts, gangs, criminals, rogue supremacist groups, religious zealots, and others. How do we stop them? How are we going to find them, disarm them, and prevent the tragedies that they would've caused?
Can laws solve all of the problems concerning gun violence and deaths?
