Should cops be patrolling schools?

About forty percent of the nation’s local law enforcement agencies have full-time officers policing public schools. That’s according to a Congressional Research Service report from 2013. Police are responsible for school security in New York, Chicago, Philadelphia, Los Angeles, Miami, Houston and many other school districts across country. Having cops in schools has coincided with a decline in crime. But some critics say it can make troublesome behavior worse and actually steer kids into the criminal justice system.
