Staten Island —

It’s a frigid morning on Staten Island’s South Shore, with the temperature struggling to crack 20 degrees as a stiff wind buffets the Eltingville neighborhood. The elementary school students showing up at P.S. 55 are cocooned in puffy jackets, gloves and hats as they jump out of warm cars and onto the sidewalk towing large backpacks, some adorned with the face of Justin Bieber, others with the logo of the New York Giants.

Amidst an ongoing school bus strike, it’s a fairly orderly scene on this Tuesday. Parents drive up to the curb, let their children out and move on to the rest of the day. Directing traffic, and gently scolding the occasional parent who pulls a U-turn on Koch Boulevard, is Mike Reilly, a former New York City police lieutenant who is a few days shy of his 40th birthday.

Reilly is outside the school each morning mostly to mitigate traffic. But, as the co-author of a controversial school safety plan that calls for the Department of Education to use retired cops armed with guns to protect city schools, he’s also found himself in the middle of the contentious debate over gun control and student safety that has erupted in the wake of the December massacre at Sandy Hook Elementary School.
