全世界人性都一样

Quora最佳问答（Best of Quora 2010-2012）里有一个问题：What have you learned as a police officer about life and society that most people don’t know or underestimate?（当了警察，你发现了些什么你过去不了解或者一直忽视的东西？）

一退休警察兼刑事审判教授（Tim Dees）的回答获得最多评价，我也觉得若有所思。其答案如下：

1. One of the things my upbringing did not prepare me for was the complete lack of civility that some people have. I didn’t think of myself as having been sheltered from evil as a child, but I did not learn that some people have absolutely no regard for the welfare of anyone but themselves, and lash out at anyone who tries to make them aware they are not the only people on the planet.
2. Everyone has a “hot button.” Calm and even-tempered as you might be, there is some topic that will set you off, especially if it’s referenced to you personally. It might be your height, your weight, your sexuality, your education, how much money you have, your mom, whatever. Rational people can become maniacs if someone pushes their buttons.
3. Although they may not know it, there are people who find these hot buttons instinctively, and they live to push them.
4. Never underestimate what people will do for sex, money, and/or power. That applies to everyone, from the basest criminal to the most saint-like person you know.
5. People can be sexually aroused by almost anything.
6. There are practices people engage in for sexual reasons that you will find baffling and utterly disgusting. You can gain some limited insight here by going to a reasonably-well-stocked adult bookstore and examining the diversity of the materials. If your thing is watching overweight Asian women give each other enemas, there are not just other people who enjoy the same thing, there is probably a regular magazine and series of videos devoted to it.
7. No matter how bizarre you find other folks’ sexual preferences, you have to be at peace with knowing that what consenting adults do in private is their business alone. If they decide to take it public or engage people who either don’t consent or are too young to do so, you can get involved.
8. Law enforcement is a very stressful occupation, but most of the stress comes from the political interactions and power games within each law enforcement agency. The stuff on the street can be stressful, but you learn to deal with that quickly or you get out. About half of the people who become law enforcement officers leave before they have five years on the job. Some get fired for unsuitability, incompetence, or misconduct, but others find out it’s just not for them.
9. High-speed chases look like fun because they are.
10. Once you become a cop, very few of your non-cop friends will ever again treat you the same way. You will be introduced by your profession for the rest of your life. People are never going to be comfortable with the group charged with detecting and making them accountable for their bad conduct.
11. Many criminals can be reformed, and eventually do come to the point in their lives that a criminal lifestyle is more trouble than it’s worth to them. Unfortunately, by the time some of them do that, they have incurred a prison sentence that will keep them behind bars until they die.
12. Criminals who do not fit into the above category are mostly predators, and should be locked up permanently.
13. Never say, “Now I’ve seen it all.” There will always be innovators.
14. Take away alcohol and stupid, and the world would require about 90% fewer cops.

他的答案，从一个警察的角度来分析总结了这个问题，涉及到人性中方方面面，尤其是性、金钱、权力，全世界的人们都一样。
