Here's a macro view, from James A. Johnston, written in 1949:
Because local peace officers were handicapped and limited in
jurisdiction, the professional criminals had little fear of them, and
no concern about State and County boundaries. State boundaries were
barriers to the officers of the law, but meant nothing to the bandits.
Beginning in 1934, the passage of the Federal laws to punish bank
robbery, the strengthening of the F.B.I., the segregation of Federal
prisoners and the establishment of Alcatraz all contributed to the
rout of the roving robbers.
The night burglaries and daylight holdups perpetrated against banks
with increasing frequency, increasing boldness and increasing losses
in the late 1920's and early 1930's, reached a peak of 631 in 1932,
with 77 burglaries and 554 holdups. Soon after passage of Federal laws
and the development of efficient cooperation between local, county,
state and federal forces, the gangs began to break and run to cover,
but wherever they turned, FBI agents and local police cornered them.
The bank burglaries and holdups went down year by year, from 631 in
1932, to the low water mark of 26 in 1943. The efficient enforcement
of the law responsible for this reduction, meant more effective
protection of property, as well as the safeguarding of human lives.
When the bank robbers were running wild, the burglary insurance rates
mounted to almost prohibitive figures, but when the burglaries and
hold-ups went down year by year from 1932 to 1943, the insurance rates
dropped correspondingly, and bank directors and stockholders saved a
lot of money.
Mr. Johnston was a banker by profession, his outlook and statistics
were from banking sources. He references the American Bankers
