NO, by providing firearms to teachers (aka civilians not trained to respond tactically to a threat situation) you create a potential for more confusion and accidental casualties unrelated to the actual threat in the event of an attack (especially pertaining to a mass shooting event when it has been seen repeatedly that the whole "good guy with a gun" argument falls flat when said person can be mistaken for the shooter and inadvertently be seriously injured or killed by law enforcement during the chaos). Instead we should focus on stricter gun laws that remove firearms from civilian usage and provide more mental health care for the public. There are far too many risks and liabilities that outweigh the supposed "advantages" for a teacher to carry a firearm.
