Show of Hands

Teachers should be paid on performance like everyone else.

Uh.. no. Pistols for those that consent and are able to pass checks.

There wasn't a correct answer option. The correct answer is ".38 caliber revolvers." They are more reliable and easier to use than SA handguns, and can be concealed or open carried. So-called "assault rifles" (more properly described as "lightweight semiautomatic sporting carbines") are not appropriate for teachers because they cannot be carried concealed and can't be securely stored in the classroom and still be instantly accessible, without installing fingerprint-lock gun safes in every classroom.
The most important solutions are to tear down those awful "GUN-FREE ZONE" signs that advertise soft targets, and lock all but the main entrance to the school and staff that entrance with two armed security officers who will check all backpacks (AND trenchcoats!).

Teachers don’t do their jobs for the money they do it because they chose to do it.

Sustainable infrastructures & realistic policies

Pistols seems most approperate.
