Observation

All students in primary school should be taught periodically how to react, what to do, and what to remember if they witness a crime or are the victim of a crime. They should also be taught to whom they should report the crime.

Penalties

All students should also be taught what the penalties are for a whole variety of crimes and how to estimate what the penalties would be for various fictitious crimes. This may help dissuade at least some people from both current and future criminal behaviors.
