Brown added that mental health should be considered in efforts to prevent future shootings.
"I also think we need to look at mental health in this country and see if we can keep these weapons out of the hands of people with severe issues," Brown said. "I think it's time for all of us to have these conversations."
In July, shortly after a shooting rampage at a movie theatre in Aurora, Colorado Brown signaled that gun restriction legislation should be left to state legislatures.
"Scott Brown supports the state assault weapons ban here in Massachusetts, and believes that the states are the appropriate venue for making these types of decisions," Brown's office said according to the Associated Press.
