The DOJ’s COPS Office supports community policing through the sharing of information and financial grants. The COPS Office states that “[c]ommunity policing begins with a commitment to building trust and mutual respect between police and communities. It is critical to public safety, ensuring that all stakeholders work together to address our nation's crime challenges. When police and communities collaborate, they more effectively address underlying issues, change negative behavioral patterns, and allocate resources.”
