"A Yellow Light for Red-Flag Laws
By Alan M. Dershowitz
President Trump's proposal to "red flag" potential mass shooters is well-intentioned. If we could prevent even one mass killing by identifying and disarming the potential perpetrator beforehand, it would be worthwhile. But do we have the tools to do it, and at what cost to our constitutional rights?
I have studied, taught and written for half a century about the difficulties of predicting violence. My first scholarly article, in 1970, was titled "The Law of Dangerousness: Some Fictions About Predictions," and a subsequent book was titled "Preemption: A Knife That Cuts Both Ways" (2006). Research shows that any group of people identified as future violent criminals will contain many more who won't be violent (false positives) than who will (true positives). More true positives mean more false ones. Such groupings also fail to identify many future violent criminals (false negatives).
Be wary of denying individual rights based on predictions.
