Democratic candidate for attorney general Warren Tolman has released a new television ad focusing on the issue of guns.


The ad shows Tolman outside the National Rifle Association's headquarters in Fairfax, Virginia, pledging to push for so-called ``smart gun technology,'' including fingerprint trigger locks, on all new guns sold in the state _ something he's said he could do without new legislation as the state's top law enforcement officer.


In the 30-second spot, Tolman also points to his efforts as a state lawmaker to force tobacco companies to disclose ingredients in cigarettes.


A spokesman for fellow Democratic attorney general hopeful Maura Healey said she also supports smart gun technology, but would push for a more comprehensive plan to address gun violence.


Gov. Deval Patrick recently signed a sweeping overhaul of Massachusetts' gun laws.
