Every solution to mass shootings inevitably involves a serious trade-off
ByDan McLaughlin
What can we do? What should we do?
The answers are not easy, and they inevitably involve a trade-off: accepting the unacceptable, or restricting our freedoms. The three big ones are freedom of the press (publicity gives oxygen to these kinds of acts, so restricting coverage will reduce copycats); the right to bear arms (guns don't cause human evil, but of course they make it easier to carry out); and due process (targeting potential mass shooters, or mentally ill people in general, is possible, but requires us to curtail Americans' civil rights before they have actually committed a crime).
It is by no means clear that any of these solutions would be more effective than the others, and each of them involves punishing a very large number of people in order to stop the evil-doings of a very small number of people.
The knee-jerk reaction is to go after firearms, but there's a bait-and-switch element to gun-control arguments in these situations. Activists focus on small restrictions that are palatable to many. If anyone points out that small restrictions won't do much to stop shootings, the activists argue that larger restrictions, unpalatable to many, would do the trick.
Gun owners are used to hearing, almost in the same breath, "we'll stop shootings by banning all guns" and "nobody's trying to take your guns away."
