Disuasión de crímenes masivos

(Pase de taquito de NQ) Un debate interesante (es un audio) es el siguiente:

Sanity Squad: What Went Wrong at Virginia Tech?
The Sanity Squad is composed of 4 mental health professionals, Neo-neocon, Dr. Sanity, Shrinkwrapped, and Siggy.

En este debate refieren a la siguiente investigación(otro pase de taquito de NQ) :

"Multiple Victim Public Shootings, Bombings, and Right-to-Carry Concealed Handgun Laws."
By John Lott and William Landes

Abstract
Few events obtain the same instant worldwide news coverage as multiple victim public shootings. These crimes allow us to study the alternative methods used to kill a large number of people (e.g., shootings versus bombings), marginal deterrence and the severity of the crime, substitutability of penalties, private versus public methods of deterrence and incapacitation, and whether attacks produce "copycats." Yet economists have not studied this phenomenon.

Our results are surprising and dramatic. While arrest or conviction rates and the death penalty reduce "normal" murder rates, our results find that the only policy factor to influence multiple victim public shootings is the passage of concealed handgun laws. We explain why public shootings are more sensitive than other violent crimes to concealed handguns, why the laws reduce both the number of shootings as well as their severity, and why other penalties like executions have differential deterrent effects depending upon the type of murder.

Es decir, se encuentra que el que la gente pueda portar un armas escondida sí que sirve como disuasión para los crímenes masivos. Otras penas como arresto, condenas más largas o la pena de muerte no afectan mucho la incidencia de los crímenes masivos.... Un aporte al debate. Tocará seguir investigando. Obviamente, no es la última palabra. No es ni siquiera claro que la pena de muerte sí sea disuasiva de crímenes "normales" (ver ¿Salva vidas la pena de muerte?).
