TRENTON - Parents of children killed in the Newtown, Conn. school massacre were in Trenton today urging lawmakers to toughen gun laws.

The parents came to show support for a bill to reduce the legal limit for ammunition magazines from 15 to 10 rounds.

One mother of a Newtown victim says limits on firearms give victims a fighting chance. "In approximately four minutes he shot 154 bullets, and killed 26 women and children," says Nicole Hockley. "Five of those bullets hit my son and in an instant my precious boy was gone."

Gun control advocates believe if a shooter has to stop to reload, it gives victims in a mass shooting more time to run.
