ATF Found 500 Violations at Gun Store Linked the Sandy Hook

My local paper, the Journal News (you know the one that got slammed for printing names of gun owners here), with probe that found that the gun shop that sold that Bushmaster to Adam Lanza had previously been cited for 500 violations by the ATF--but only shut down after the Sandy Hook tragedy. 

Among the “willful violations” found from January 2010 to July 2011 at Riverview Gun Sales in East Windsor, Conn.: A senior store employee “sold ammunition on at least two occasions” to a man “he had reason to believe was a felon.”It’s the same employee who sold the Bushmaster XM15 rifle to Nancy Lanza on March 29, 2010, that her son, Adam Lanza, used at Sandy Hook Elementary School to kill 26 people on Dec. 14, ATF records show.
