We have more gun control laws than ever and they are not changing anything. The problem is not the guns, which were far more readily available 50 yrs ago when mass shootings were extremely rare.
The problem is the mental health epidemic, the willingness to kill innocent kids because YOU are mentally ill and hurting, the hate and willingness to use violence against some one just for disagreeing with your beliefs.
The problem is the loss of basic humanity among the people doing these things. Its insanity to claim more gun laws alone will change this .. there has to be more to it.
