So you agree that Usman Khan aliyas Md Yakub should be considered for death penalty? I'm not expecting others to stop terrorism after hanging him but stopping him from committing further crimes.
Abolishing death penalty is thereotically exciting but practically death penalty is more logical & economical.
We badly need judicial system reforms, just Swift hearing and proper judgement acts as a strong deterrent for many people. Our current social & political scenario isn't appropriate for abolishing death penalty.
What is the basis of that article. It looks like it is simply general public opinion and opinion of some criminologists which was also formed based on data collected from the public. There is no indication of data from actual criminals and wannabe criminals. (which is hard to capture) So, there is no hard data there to prove that death penalties doesn't deter crimes. There is only data to indicate that a lot of people and a number of criminologists out of their sample size think that death penalty doesn't deter crime.
Even otherwise, that article does not seem to have any relevance for our country. The background of the country is important and does matte. British law which we inherited for instance is based on the fact the premise that most people can reformed with a bit of correctional punishments and it does not really work for a country like India.
How do you decide whether death penalty is a deterrent or not. Here is how we can go about it?
1. Are there at least 10 people (may be even 1) in the country who would refrain from committing a heinous crime because of fear of the punishment they would get when they get caught?
2. Does having this punishment have any other negative impact on crime rate?
3. How does it fare compared to another measure. For instance if you take two people who like to commit crimes for the heck of it and tell the first one that he is definitely going to be executed if he commits a crime and the tell a second one that he will be made to sit though a one month rehabilitation program with all costs borne by the govt and would be allowed to go free after that. Who is more likely to commit a crime?
If even 10 crimes are prevented because of having death penalty in our system, then it has already fulfilled its purpose as a deterrent.
