Metal Detectors/ X-ray machine for Odessa School's

I'm am concerned for our children's safety. No child or Adult should be able to get a gun onto campus unless it's a staff member . Why take that risk. In the past week their have been two instances involving a gun at our School's. We NEED METAL DETECTORS/X-ray to keep our schools safe! What other options do we have to keep our children safe? There are none.
