One study noted two important difficulties while implementing the community problem-solving strategies of CAPS. First, better results were found in "high-capacity" beats where citizens' economic and social statuses were much more secure and the population usually had more in common with the police population. These same neighborhoods tended to have a more positive perspective of the police after the program. In comparison, what were deemed "low-capacity" areas held a more diverse population with little interest in the community as much of the people were renters who lived there for under 5 years. The areas tended to have high concentration of crime and leadership was much less likely to implement problem-solving and community techniques leading to complete failure. Second, racial divisions in some of the more stable communities where the program looked to be promising led to lack of coordination. Beat officers had a difficult time mediating while sticking to the regulatory style their position requires.
