If education is made accessible to all, people will be encouraged to study, improve their education and lifestyle and be too busy studying to even think of crime. Fourthly the economy of the country needs to be addressed to enable stability and growth. Through running the country as a business and employing proper business strategies this can be achieved. Put a clamp on all credit card spending in government, restrict corruption, stop the gravy train, limit overseas travel to absolute bare essential, improve the country's cash flow, improve the tax collection service and get everyone to pay tax, etc. Once the economy is going at an acceptable rate, crime should decrease.
Crime is like a growing cancer.
The cancer has spread too far.
