Warren PAL

PAL is a youth crime prevention program that utilizes educational, athletic and recreational activities to create trust and understanding between police officers and youth. It is based on the conviction that young people if they are reached early enough, can develop strong positive attitudes towards police officers in their journey through life toward the goal of maturity and good citizenship.

The PAL program brings youth under the supervision and positive influence of a law enforcement agency and expands public awareness about the role of a police officer and the reinforcement of the responsible values and attitudes instilled in young people by their parents. Studies have shown that if a young person respects a police officer on the ball field, gym or classroom, the youth will likely come to respect the laws that police officers enforce. Such respect is beneficial to the youth, the police officer, the neighborhood and the business community.

Our website is designed to educate the community on the advantage PAL has on our community as well as recruit new members to our program and provide as a resource to current PAL members.

Our programs are open to all Warren Residents (programs have age restrictions, see the sports page for more information).
