Another highly debateable issue. You should have no problem getting arguments to last generations.
Some other countries have MUCH lower populations, thus much lower numbers. The per capita issue.
Some other countries have MUCH lower percentages in prison because they have instant retrobution against law breakers. Decapitation, bullets to the head, etc. Brutality replaces penal system issue.
Some other countries have MUCH lower crime rates. They disarm thier citizens, take away freedom of speech, strictly regulate the activities of the population, remove all influences of the rest of the world via communications. In short they are not free in any way.
SOme countries such as ours, with a constitution, laws created by the people, of the people, with a huge judicial system, prison system in a free society where there is no set standard where laws cannot be changed. A country where the press is not inhibited. A country where immorality can be sold on the street, in television, in commercials, in movies, and all sorts of media and glorified by all these means because it is the right of the citizens to choose. Where drug flow is impossible to stop, where guns are easily accessed, where poverty can ruin the values of the childen. A country where anyone can be influenced by good or bad with no one to decide for the individual what is right because that is a violation of their rights. A country where it is almost legal to do anything, and we still hear the cries of injustice for the ones who are jailed for what is still not legally acceptable behavior or actions. Our laws are questioned and challenged each and every day by all sorts for virtually any reason, and they are given the opportunity to be heard at least at some level of the justice system. Yet we are ridiculed by all the pacifists of the world because we are too harsh. Too many in prison.
For some there is no acceptable society that has prisons. Just let everyone go, to be free to do harm to its citizens, because surely they wouldn't do these things if the government hadn't failed them in some way. Educate them they say. Treat them with medical care they say. Dont regulate morality in any way. Ethical standards are individual preferences and we have no right to decide what is good or bad. Ah the perfect society... America is not the perfect society so we are condemned by the other less than perfect societies of the world, and their citizens outside looking in. Its always easy to judge and pass judgement for those who dont participate in its workings. Where are all those perfect people? Will they take one of our prisoners and take them into thier homes and take responsibility for thier actions? Im betting the government would be happy to release them all to anyone willing.
