TRENTON - Rep. Bonnie Watson Coleman (D-12) will introduce a bill in congress Tuesday to place restrictions on the sale of ammunition online.

The bill would require that federally licensed ammunition dealers confirm the identify of their customers by verifying a photo identification and if those customers purchase more than 1,000 rounds within five consecutive days, their identifies would be passed along to the U.S. Attorney General.

"This gives the ability to monitor large ammunition purchases and flag them for law enforcement," said Watson Coleman, speaking at a press conference at the Serenity Garden at the corner of Prospect Street and Bellevue Avenue in Trenton.

"There are plenty of ways that we monitor the purchase of firearms, but when it comes to ammunition regulation seems to stop," Watson Coleman said. "There is nothing keeping an individual intent to commit a large-scale atrocity from rapidly and anonymously stockpiling the means to do so."

Watson Coleman has support from her congressional colleague and co-sponsor Frank Pallone (D-6)

Pallone said the proposed legislation would help to prevent mass shooting incidents like the 2012 Aurora, Colo. shooting that killed 12 people at the Century movie theater. James Holmes, who is currently on trail for the shooting, is said to have amassed an arsenal of thousands of rounds of ammunition purchased online.

"You kind of think of it and say how in the world can there be opposition," Pallone said, noting that it is difficult to get these kinds of legislation passed in the Republican- controlled House of Representatives.

John Jenkins, the stepfather of Tre'Devon Lane, who was a victim of gun violence in Trenton in 2012, said he hopes that these changes might help stop other families from feeling the same kind of pain his family still feels for the loss of Lane.

"Yesterday was not a happy Mother's Day for my wife," Jenkins said. "She lost her only child to gun violence."

The Million Mom March also supports Watson Coleman's legislation calling it "incredibly reasonable."

"A consumer product that has the ability to kill should be regulated like cigarettes and certain allergy medicines," said Carol Stiller, president of the New Jersey Million Mom March chapters.

"Common sense isn't so common because if it was this would have been done already," Trenton Mayor Eric Jackson said in support for the bill.

"At the end of the day anyone who would amass mass numbers of ammunition, the intent has to be something that is not going to be helpful to our cities and to our communities," Jackson said.
