Libertarian conservatives believe in limited government intervention and individual responsibility, and therefore, offer a smart on-crime solution to this problem. This solution focuses on reducing the number of criminal laws and reforming the criminal justice system to prioritize the prosecution of serious crimes and reduce the burden on the system.

One way to reduce the number of criminal laws is to reconsider the criminalization of victimless crimes, such as drug offenses, prostitution, and gambling. Instead of criminalizing these activities, the government could regulate them and provide education and treatment programs for individuals who engage in them. This would reduce the burden on the criminal justice system, freeing up resources to focus on more serious crimes.

Another way to reduce the number of criminal laws is to streamline the criminal code by consolidating similar offenses and eliminating redundant or outdated laws. This would make the criminal justice system more efficient and easier to navigate. Additionally, reducing the number of criminal laws would also reduce the number of people who are incarcerated, reducing the burden on the prison system.

Reforming the criminal justice system is also an important part of a smart-on-crime solution. This can include implementing evidence-based programs and policies, such as rehabilitation and reentry programs, to reduce recidivism rates. Additionally, the use of alternatives to incarceration, such as drug courts and mental health courts, can also be effective in addressing specific types of criminal behavior.

Finally, ensuring that the criminal justice system is transparent and accountable is also important in creating a smart on crime solution. This can include implementing reforms such as body-worn cameras for law enforcement, increasing transparency in the grand jury process, and improving the accuracy and reliability of eyewitness testimony.

In conclusion, the over-criminalization problem in the United States can be addressed through a smart on crime solution that reduces the number of criminal laws, reforms the criminal justice system, and prioritizes the prosecution of serious crimes. This solution aligns with the principles of libertarian conservatism, which values limited government intervention and individual responsibility.
