You talk so much about how giving a person help would prevent others from killing when you fail to realize that someone could claim they are "better" and deceive you then start killing. How many chances do we have to take before we realize that there is o cure to cold blooded murderers?
There is no "cure" to cold blooded murder. Thats no illness but an offence.
The victims of that would be glad if someone had helped them beforehand and brought that scum, who attacked to justice, so they would be safe from him.
The problem with your theory is that it's very hard to predict who's going to murder. Besides, even if you do bring someone into jail when they attack someone, they will still kill someone after they get out. I'm sorry but I just don't see where you're going with this
following your excourse, one should let a murder happen, instead of helping and execute the murderer afterwards, cause he would have killed anyway? Did i get that right?
There are murderers who can't be detected is what I am trying to say. How do you detect a murderer who cannot be detected?
You can try to detect a murderer by good police work and a stable society and bringing those to justice which did commit a crime.
Remember New Orleans.
They had the death penalty. Yet after that terrible storm murder and rape was daily life on the streets.
Why? Not because of existing DP, but because those guys knew they would not been caught.
Remember Mylai. The Officer who ordered it spent two years in jail only.
More important than DP is a society that protects all and for offenders the knowledge that they will not get away with crime.
DP ist costly, arbitrary, punishes only a few poor sods using resources which are missing at much more important places as child education, drug prevention and rehabiltation, poice work and finally for the help of victims of crimes.
