Politicans pushing for public gun crime database – They can gun, but they can’t hide.  A registry of criminals convicted of gun felonies would be publicly accessible for the first time under legislation being proposed by a group of elected officials.  City Council members Costa Constantinides and Paul Vallone, along with Bronx Borough President Ruben Diaz Jr., are calling for the database created in 2006 — currently available only to law enforcement — to be searchable online.
