Make it law that all schools are required to hire atleast one policeofficer to protect our nations children

We should enact into law that all schools are required to employ atleast one full time officer to protect our nations children to prevent future cases like what happened in newtown conneticut. Having an armed officer could havr potentially saved the lives of those children, and could prevent this from happening in the future, also this would provide more jobs for police officers which seem to be getting laid off constantly because of the state of our economy
