Yes i agree, during to decrease crime, of course, it is time to confront effect of crime like poverty and lack of educational oppurtunities. It is just not enough to increase police presence and kept lots of people to the prison. It is caused by two reason, some people does not has fully knowledge for behave in life until their got a crime and the punishment cannot encourage some people to aware.
Recently, many people into prison because their does not understanding what they do, they should get an education to act properly for their life. So, i think the government should provide their assistance to the cityzen such as seminar, because not everyone could has a chances to improve their personality. However, if they already did a crime, they should pay attention to the impact of the crime as a result they can fix this action for the next time.
In the other hand, the penalty from the police to take care us from the crime is not enough to afford. Some punishment only gave them a temporary pain. In addition to fix this case, i would say the police have to let them to do some job in the prison, for example, helping the police to maintain the prison environment or learning a lots of new hobbies in the prison to add some good experience.
To conclude, we all already knew that to reduce crimes some police assistances and the punishment are not very inadequate. So, the police have to improving people from the crime in order to produce something positive with giving some knowledges.
