What were the findings of Professor Land and his colleagues' death penalty deterrence study of homicides in Texas from January 1994 through December 2005?

Modest short term deterrent, but will need mass executions to be effective

Modest short term deterrent, but will need mass executions to be effective

Explanation:

The question has already been answered but I guess you need an explanation.

In the deterrence theory by Professor Land and his colleagues, they assumes that offenders are rational, I.e. they know the law and the penalties attached to defaulting the law..

They're are three points to take note of in this study;

1. For execution to have a deterrent effect, then it means a huge number of execution must have taken place

2. Most of any deterrent effect of execution of homicide occurs immediately after the execution is made public

3. 5 to 10 homicides would deterred in a year if there are 10 to 20 executions using 0.5 homicides deterred on a monthly basis.
