But while many have called for stricter gun laws in their wake, the Post-ABC poll finds far more point to problems treating people with mental health issues. By a more than 2-to-1 margin, more people say mass shootings reflect problems identifying and treating people with mental health problems rather than inadequate gun control laws (63 percent to 23 percent).

There are wide partisan divisions on this issue; 82 percent of Republicans say shootings reflect a failure to identify and treat people with mental health problems, compared with 65 percent of independents and 46 percent of Democrats.

Americans have strong opinions about overall priorities in the gun debate, with big divisions by partisanship, between cities and rural areas, and between men and women.
