Problem-oriented and community policing are often contrasted. In this paper we evaluate the impact of a police crackdown that incorporates ingredients of both approaches in an effort to neutralize tenants of a troublesome flophouse. Weekly 911 calls by tenants of all block apartments located in a Montreal neighborhood are analyzed. The evaluation design isolates the specific effects of both ingredients. Findings show that intensive patrol surveillance increases residents’ propensity to report disorders and that the strategy to reduce disorder levels by targeting place managers and other agencies was not particularly successful.
