There appears to be an increase in murders in places were legal firearms are banned. There are 3 million AR 15 s in circulation. People are proposing restrictions going forward. So the carnage continues. How about communities setting up groups of citizens willing to be guards at schools, movie theaters, mall, etc in exchange for concealed carry permits. However, to qualify they would have to take a hands on course provided by their local police department to train them to handle hostile shooter situations. This puts more QUALIFIED people to protect those who can't or choose not to protect themselves. This way if another psycho decides to take out innocent babies or adults either with one of the 3 million AR 15s or any other weapon there are people TRAINED to contain the situation until the police arrive. It may not be the perfect solution but its better than most I've read. Many would probably volunteer for no pay or minimum wage.
