Impact Wrestling star Tyrus says he knows exactly how to STOP SCHOOL SHOOTINGS ... put up walls, install metal detectors, and station armed security outside entrances.
TMZ Sports talked to Tyrus -- who's also a contributor on FOX News -- after the latest act of violence at a Maryland high school.
FYI -- "The Fixer" knows a thing or two about protecting people ... he used to be Snoop Dogg's bodyguard.
Tyrus' plan to stop the killings in schools? Walls, guards with guns, and metal detectors ... not teachers with handguns.
