make it a law to have metal detectors and security in ALL schools and security check IDs and sign in visitors at door

Petition to bring into law the use of metal detectors in ALL schools and to have professional security on ALL campuses and to have security at all entrances checking EVERY non-students ID and making them sign in on a log. 2 kids walked into the high school on my sons campus yesterday with a RIFLE and SHOT A GIRL!!!!! There is NO REASON 2 kids should have been able to get a RIFLE ON CAMPUS!!!!! It was out in the open enough that they could see it later on surveillance videos... but nobody saw it or stopped it. And they are ONLY adding metal detectors to THAT school... does someone have to die at each school for them to wise up and decide to keep our kids safe??? The government legalized guns... now they need to make a law to protect the innocent from the idiots that use them
