An excellent summary from Heritage:
When confronted with the murder of children, the only reaction is anger, shock, and grief. Since the massacre at Sandy Hook Elementary School in Newtown, Connecticut, America has been reeling.
We want to protect our fellow Americans, our families, and ourselves. We want to understand the causes of violence and meet the challenges before they turn into tragedies. On this, we can all agree.
To be effective, the response to Newtown cannot be a hasty “Do something—anything” response. That’s why Heritage experts have taken the time to consider the complex problems involved.
