People do a lot of things every day. Some of those things are intentional, and some are not, but we are definitely affected by all of them. The consequences are both positive and negative. If the negative effects are big enough which really influence your life, you could feel sad, because of the bad things you have done. For example, if you drive a car when you are drunk, you will have broken the law. For those people who work for the government, they could even be fired. So, in order to reduce crime, *nafitve* {I DON'T UNDERSTAND THIS WORD: what do you mean to say here? Who posts?} examples about crime often post online which teaches us a lesson and tells us how we will be punished if we commit the same crime. It really works. Next time, if we had the chance to do some bad things, the pictures of people who have done the same things and have been thrown in jail would suddenly come into our mind, then we would not commit the crime and would avoid negative effects which would ruin our lives.
