Will they give guns to all the teachers, good and bad alike? Then I guess we will find out if the good teachers with guns can stop the bad teachers with guns.
The law is not issuing guns to teachers, it's allowing teachers to concealed carry in a school if they pass some tests and get approval from a few relevant people. The data says it's ineffective at having the intended effect (stopping school shootings) but apparently already 2/3 of states have a similar policy. Anyway, if you want to learn how to stop school shootings I suggest you read Angry White Men by Michael Kimmel.

So in other words, the gun laws teachers are subject to may actually be effective for stopping dangerous and negligent people from owning a firearm but we can't apply similar policies to the public because it would inconvenience reactionaries and weapon manufacturers.
This law has nothing to do with owning a firearm. It is only about who can concealed carry and where. The law in this area is highly variable, changing even from city to city.
I didn't claim it had anything to do with owning a firearm. You either misunderstood my comment or are deliberately trying to pretend I don't understand the law.
"The teachers are getting additional vetting (to carry within a school) that could be effective and appropriate for all gun owners, but they get a pass"
Well okay, that's a perfectly valid opinion but it's not the one you originally stated, even if you didn't mean to. They're both valid opinions actually, it's just that the distinction between the two is important because we're dealing with the law, where details matter.
Speaking of which, I must re-emphasize, "they get a pass" really depends on the state and city, but even in the most permissive jurisdictions there's still limits on who can carry or concealed carry and where.
