"Not learned to be law abiding" Seriously, criminals in most cases know outright that they are breaking the law (unless they are not guilty by reason of insanity or some other extenuating circumstance).
Knowing that a law exists is not the same as being able to follow it. How many people in the US are committing crimes every day because they don't have the willpower to overcome destructive patterns of behavior? Anybody who smokes pot, drives over the speed limit or doesn't declare cash income is committing a crime. They tell themselves that the law is stupid, or what's the harm, or that they are entitled to it. But still they are
breaking the law, and have the same mindset as rapists and murderers.
And how the hell does executing the most heinous criminals "perpetuate the cycle of violence".
Apart from the obvious fact that someone who is already facing the Death Penalty has more incentive to kill witnesses and go on a crime spree, it teaches people that the answer to their problems is violence. Certainly we need to catch criminals and stop them from committing more crimes, and that often requires force - but it doesn't mean we have to add
more violence to the equation.
'Fighting Fire with Fire' may work in desperate situations, but most of the time it just causes even more destruction. The Death Penalty is the State's message to us they have a monopoly on carefully planned and executed cold blooded murder. We should consider any execution to be the ultimate failure of society's efforts to teach people not to hurt others (and themselves), but the DP is teaching us that killing is the
solution. Criminals read that message to mean that they too are justified in using violence to solve their problems. If you believe that violence is the answer then you are part of the problem, not the solution.
As for your NSA point, would you like the government creating a panopticon state which monitored confidential calls (say you are going through something like a nervous breakdown or a divorce, your situation would be made even worse if you thought the government was monitoring your every move).
Yes, I would be happy with the government constantly monitoring people and intervening when they are about to go off the rails, provided that it is done to
help them (and not for corrupt purposes such as filling up for-profit private prisons).
That's a big ask because it requires us to set aside our fear of 'big brother' and emotional responses to crime, but until we stop thinking of criminal activity as a character flaw and treat it like any other mental health issue we will never get ahead. What many people don't realize is that criminals
do suffer from mental health issues, and this is the root cause of their mental state. Unfortunately by the time we discover this (if ever) it's usually too late. Monitoring people for signs of mental instability allows us to catch and treat their illness
before it passes the point of no return where heinous crimes are committed. Any right-minded person would welcome that help.
By that standard, do you advocate waterboarding people and the use of polygraphs (after all, nothing to hide, nothing to fear)
No, of course not. There is a world of difference between surveillance and torture, and the polygraph is just a prop that interrogators use to fool subjects into thinking they can't get away with lying.
Lastly, humans are emotional beings, and if a friend or relative was beaten to a pulp and/or shot, you would be calling for the killers to get the noose just like anyone else.
Actually no, I wouldn't. I have come to realize that anger is not a useful emotion, so I would only feel sad for the loss. I would also feel sorry for the killer, for being so sick and beyond help. It would be a tragedy all round.
Anyway, you put far too much faith in SCIENCE! to solve societal problems
If not science then what else? We cannot trust our emotions, religion is a crock and traditional methods are not working any better than they did a thousand years ago. Applying
science is the only way to move forward.
remember there were scientific journals in the 1920s arguing that black people were inherently dumber than white people
Some still do, but the rest aren't buying it. Why not? Because science has to conform to
reality, not preconceived notions and folklore. Ask any scientist studying human cognition or social behavior, and they will tell you that the idea of criminals being 'evil' is outmoded and unproductive, just like traditional concepts of 'race'.
The more we use
science to learn about the human brain and why we behave as we do, the better we will be able to deal with the mental issues that cause crime. And
science also gives us the technology to detect crime, identify those who are at risk, and produce the medicines that will treat it. The only alternatives are ignorance and superstition.
