Four northeastern governors including Gov. Tom Wolf on Oct. 7 signed a Memorandum of Understanding to share crime gun data in an effort to prevent gun violence and enhance public safety. The agreement allows law enforcement agencies from Pennsylvania, New Jersey, New York and Connecticut to share crime gun data across state lines in order to detect, deter and investigate gun crimes, as well as identify and apprehend straw purchasers, suspect dealers, firearms traffickers and other criminals.
