“In reality, we just can’t afford it,” said Hayduca, who is police chief in South Brunswick. “There’s a 2 percent cap levy on property tax increases in any given year in any given town, so I don’t know where the money would come from.

“We have 11 schools in South Brunswick. I would have to hire 10 officers at a total cost of more than $1 million to put a cop in every school. It’s just not realistic. I mean, the concept is great, but financially, you can’t do it.”

John Shane, professor of criminal justice at New York City’s John Jay College, said the measure might provide peace of mind but it would require study to determine whether or not it actually enhanced safety.
