Is the answer to mass shootings for civilians to carry more guns? The answer is NO. Read this:
As I reported recently in our in-depth investigation, not one of the 62 mass shootings in the United States over the last 30 years has been stopped this way. More broadly, attempts by armed civilians to intervene in shooting rampages are rare—and are successful even more rarely. (Two people who tried it in recent years were gravely wounded or killed.) And law enforcement overwhelmingly hates the idea.
UPDATE: another example of crazy gun culture: Utah sixth grader placed .22-caliber handgun to classmate’s head after ‘encouraged by his PARENTS to carry a gun after Sandy Hook’
