 In the summer of 1990 the police arrested 18 people and seized two machine guns as part of a crackdown on crime in the Fischer housing project.Police beefed up patrols in the project since the end of August 1990 to curtail drug dealing and violence.Marked and unmarked patrol cars spent eight to nine hours twice weekly in the 1,500-unit complex instead of the occasional drive-through they use to do the monitor drug dealing.
