The Great Depression of 1880 - 1882 brought an upsurge of unrest and lawlessness in the C.N.A., and this prompted McDowell to alter the C.B.I.'s mission to investigating subversive individuals and groups, and also to double its size. At the same time, McDowell replaced Prentice with Forsyth, who was well-known for his tough law-enforcement policy. McDowell also changed the title of the head of the C.B.I. from Superintendent to Commandant.
