Arm Teachers in American Schools?

A majority of Americans, according to a nation-wide poll, want to ban the sale of assault-style pistols and rifles to the general public.  Assault-type weapons are not needed for hunting game, nuisance creatures (such as coyotes or wolves, according to some folks), or for any normal situation.  I can easily see SWAT team members and soldiers having a use for an assault weapon.  I can easily agree that a few ex-soldiers, such as marksmen and snipers, could get a special permit to own and fire such a weapon.  BUT a normal, everyday American has no use, or need for, an assault weapon.
   The person in the Oval Office of the White House is in complete disagreement with me.  He thinks having more guns available to more people will make an end to these horrific killing rampages.  His Secretary of Education stated that we need more armed teachers to defend students from the attacks of grizzly bears inside classrooms.  The latest killings, at a high school in Florida, have sent young people into marches and protests.  It's sad to realize that the Columbine High School shootings took place almost 20 years ago, and this country is still gun crazy.  Mass shootings at schools, universities, clubs, cinemas, and music venues have become a sickening stream.
   Having been a teacher, at multiple grade levels, I can honestly say that I would never want to be carrying a weapon at a school, in a class room, or even have one locked in a "safe" in my room.  Too many things can simply go wrong.  There are too many distractions in a class room with 25 to 35 students.  And students these days know how to pick a key lock; they can easily record (on a ubiquitous phone) the opening of a safe and learn the combination; and what if a person with an assault rifle attacks?  What kind of weapon is the teacher supposed to have?  A simple pistol versus an assault rifle?  If the teacher doesn't accidentally kill a student and gets a shot off at the assailant, the teacher is dead meat in a second or so, thanks to the fire power and automatic firing of the assailant's weapon.  I simply do not believe that arming teachers is any answer at all.
   We need to ban the sale of all assault weapons to the general public.  We need to ban bump stocks.  People should not be able to buy any gun at a gun show.  We need to have a very tight and strict background check set up nationally.  The background check should include a mental health examination, and a look at any/all previous complaints against the person made to any law enforcement agencies.  If a person has a record of spousal abuse, endangerment of children or family members, threats against other people for perceived or real reasons, or any conviction for physical or mental abuse, that person should be denied the purchase of any type of weapon.
   Maybe my viewpoint is a bit strong....  But I stand behind it.
