Newark plans a toy gun exchange on Friday.

Children can turn in a toy gun for a book, another toy or school supplies at the event.

The city says the event will be held from 1-4 p.m. at Nat Turner Park in the heart of Newark’s Central Ward.

This is the third year of toy gun exchanges since Mayor Cory Booker started the events in the high-crime city.

At the 2011 event, Booker admitted there is no evidence liking toy guns to violent behavior later in life.
