Everyone is entitled to their opinion, I'm not trying to discount what anyone thinks.
It is my personal opinion that those who are naughty enough to be behind bars deserve bread, water, and some vitamins. I also think that the punishment should outweigh the crime to some extent. The thought of committing a crime, especially high end crimes, should scare the crap out someone. Not the pussyfoot legal system we have now, oh please don't tread on the murderers rights. Regardless of citizenship, I think major crimes should be treated as a temporary revocation of citizenship and while incarcerated you no longer enjoy the rights or freedoms of a citizen. You get out of line you pay for it.
How about global examples. Write graffiti get caned. Makes you think twice before doing something stupid. Throw a butt in the middle of the road, $750 fine(1000S). It's steep, but oddly enough you don't see them in the street. How about minimum 6 months jail term for petty theft? Malaysia has it, and do you know how much petty theft there is? Not a lot. Drug trafficking is punishable by death(you are reminded every embarkation card), do you know how much trafficking there is? not much. Owning a bullet, let alone a gun, you will do time, usually 2-5 years. They started having trouble in the 90s with people using guns to commit crimes, but not squeezing the trigger so around 2000-1 they raised the penalties to the possibility of death for simply using a gun to commit robbery. In 2000 they had about 750 acts of robbery with a firearm, last year less than 100. Wow, make the penalty truly suck and the crime drops drastically. Shooting someone is punishable by death, regardless if they live or not, if you aim a gun at someone and squeeze the trigger, and the bullet hits them, YOU DIE. A country with 27M with 500 murder/homicide per year(including vehicular manslaughter), and 40% of their prisoners are foreign(mostly Thai, Lao, Indon and Cambodian). One stat of the US that is terrifying is that HALF of our murders are committed by youths, ... is wrong with that figure.....They aren't afraid of anything...
Making the sentences longer, doesn't necessarily equate a harsher punishment, especially when incarceration is like a summer camp. I wonder what prisoners would be like if every prison were like military boot camp..... hmmmm
