N.J. city considers adult curfew after crime spate
(AP) — PATERSON, N.J. - Curfews might not be just for kids anymore in one city in northern New Jersey.
Officials in Paterson are considering one for people of all ages in a bid to curb violence after a spate of deadly shootings.
Several experts say they believe it would be the nation's first curfew of its type to include adults. The state ACLU says it would open Paterson to legal action.
