The mission of the Tucson Police Department is to serve the public in partnership with our community, to protect life and property, prevent crime, and resolve problems. Each member of the organization is responsible for establishing the direction of the department and communicating the vision at every level of the organization. We show the way in our community by going first and guiding those who follow. We are entrusted with caring for the spirit of the organization. Each employee enhances the quality of life within our community and our department through dedicated service. Our value as police employees depends upon the respect and confidence we earn from the community and each other. The integrity of each individual, as well as the organization, is necessary for citizens to give us their trust. Without this trust, we cannot expect to form a partnership with the community. We meet challenges and adversity with perseverance to attain individual and organizational goals. Fundamental to delivery of professional police service is the fair and equitable treatment of all individuals. Whether citizen or employee, all must be treated with dignity and respect. Teamwork is essential to the successful operation of the Department. The team must include all employees working in partnership with each other and the community to attain our goals. Each of us has a personal responsibility for the success of our community. We respect, care about, trust and support each other. We respect and encourage individual responsibility, while recognizing we have a right and obligation to participate in leading our community. Police work involves repeated exposure to trauma. Over time, this can create health issues. As a law enforcement officer, my fundamental duty is to serve the community; to safeguard lives and property; to protect the innocent against deception, the weak against oppression or intimidation and the peaceful against violence or disorder; and to respect the constitutional rights of all to liberty, equality, and justice. I will never act officiously or permit personal feelings, prejudices, political beliefs, aspirations, animosities, or friendships to influence my decisions. With no compromise for crime and with relentless prosecution of criminals, I will enforce the law courteously and appropriately without fear or favor, malice or ill will, never employing unnecessary force or violence, and never accepting gratuities. I will constantly strive to achieve these objectives and ideals, dedicating myself before God to my chosen profession … law enforcement. Press left and right keys to move between tabs.
