I believe that the most effective way to reduce crime is to show people the risks of becoming a criminal. We need to make people aware of the fear and difficulties that follow after committing a crime. I would say “we need to make people aware of the potential consequences of commiting a crime”. (There is nothing wrong with your sentence at all, it’s just the only sentence that sounds like it’s not quite natural - except for this sentence I would have thought a native speaker had written this text, your English is so impressive.) As everyone knows, life after being arrested is often miserable. First, criminals are imprisoned, and life in prison can be extremely tough. Depending on the severity of the crime committed, they may have to spend many years behind bars. In the worst case, they could be imprisoned for life. There is no freedom, no entertainment, and no good food. Would you want to live in such a place? I believe most people would say no. Furthermore, life after leaving prison is also extremely difficult, as former inmates must adapt to normal society again. This is a serious problem for them. They need to find a job to survive, but it is not easy because of their criminal record. People in society often do not trust someone with a criminal past. On top of that, they may struggle to adjust to social life because they have been isolated in prison for a long time. As a result, many ex-prisoners end up returning to prison, creating a vicious cycle. In conclusion, I believe that these facts are frightening for most people. Therefore, showing the risks and hardships of being a criminal can be a highly effective way to reduce crime.
