“A new TRAC study shows that criminal prosecutions in eight of the nation’s twelve largest districts are substantially lower than they were in the past. The report is based on TRAC’s analysis of millions of Justice Department records covering the period from FY 1986 through the end of April 2007. Among the most populous districts with many fewer federal filings are California Central (Los Angeles), California North (San Francisco) Illinois North (Chicago), Massachusetts (Boston) and New York East (Brooklyn) [Table 1]. Texas South (Houston) was one of the four largest districts where prosecutions have increased.”
