To be fair (why?!!??) to criminals, I can’t think of a bank robber, or home invader are known to have done mass shootings of innocent people. The shooter in colorado was a university student. Columbine shooter was a high school student. Virginia Tech was another student. The most recent mass shooting at Sandy Hook was a 20 year old with mental problem. The person who shot the congresswoman did not have a criminal record using guns. Even the Jihadist Muslim who shot soldiers in a military base was not a bank robber type criminal.
It is obvious mental problem is what causes mass murders with guns. It will be impossible to weed out every mental candidate in country by background checks.
The only solution which will work is more people with CCP’s and trained guards/teachers at schools.
Indeed, especially since the commie teachers are churning the nut buckets out of our schools as fast
as they can. Graduates today have no patriotism, no piety, no empathy, and no scholastic skills.
We will be a very long time, if ever, restoring our country after we throw these godless, evil bastards
out on their collective tushes.
I mourn for the last two generations of our children, and the next three to come, at least.
