Boston (WBZ Newsroom)  -- "Stop Handgun Violence" has unveiled another dramatic message on their billboard along the Mass Pike near Fenway Park.

This year's message is about the "gun show loophole".

The group's chairman John Rosenthal says the gun show loophole essentially makes it easier for al quaidda terrorists to buy weapons at gun shows in the U.S., than to purchase them in the Middle East.

Jim Wallace, with the Gun Owners Action League says in response, there's no proof of that claim and says it's just a scare tactic.
 
It's estimated the billboard is seen by more than 250 thousand people every day.
