The survey also finds an increase in support for an assault weapons ban, to 51 percent, even as most Americans are in favor of encouraging more people to carry guns legally in self-defense. Further, given broad worries about another lone-wolf attack, most favor increased surveillance of suspected terrorists, even if that intrudes on privacy rights.
