Real Talk 1 Drs. Cops in class: Is 'zero tolerance' still the right approach?

It seems to happen all the time. Police are called to a school to deal with students acting out. 

Some snapshots from around the country this year: In October, in Chesterfield, South Carolina, police are called because of a fight. Nine students are arrested. In May, sheriff's deputies use pepper spray to break up a fight at a Naples, Florida, high school. Three students are arrested and 21 students need medical care. In March, New York Police Department safety agents ask a student to remove safety pins holding his glasses together. When the student refuses, the officers reportedly tackle and arrest him. What's going on in America's schools that necessitate seemingly so much police involvement? Could crime in our schools really be so rampant? During a week when the country repeatedly watched cell phone video of a student resource officer violently manhandling a South Carolina high school student, many are asking: What exactly is a school cop's job and does their presence benefit teachers, administrators and students?
