5. Obtaining Information. Recall that effective liaison with other agencies
or persons is necessary to obtain information from them.
There are not set
rules for creating such liaison. However, there is one effective method. It
is "doing unto others as you would have them do unto you." Getting information
is often made difficult. This is caused by the varying moods and temperaments
of those asked to give information.
In these cases, you must use vast
patience.
You must persevere using tact.
Failure to do so may result in
barriers. These will require great effort to overcome.
a. Once the source has been identified, personal contact should be made.
Contact the person who has immediate access to the information.
Give that
person all the allowed information you can to ensure full cooperation. Use a
business-like approach. Be courteous, diplomatic, and honest in all dealings
with sources. Avoid familiarity and arrogance. Avoid, also, any appearance of
a superior attitude. Never criticize a source's method of operation. Respect
all confidences; keep all promises. Thank the source for his help. Offer to
reciprocate by cooperating when possible.
b. In some cases direct contact with a federal agency is not practical or
feasible. Then the commander, USACIDC should be contacted for help in getting
the information.
6.
Sources of Information/Sources.
a. As stated, the foundation of most successful investigations is reliable
sources of information and their proper use. Today, the law enforcement agent
is aided greatly by laboratory sciences. Other professional tools assist him.
However, these are not enough.
You are still dependent upon and responsible
for developing informants. There are several examples of cases where sources
played a major role. The capture of John Dillinger is one example. Another
was the apprehension of the Russian spy, Colonel Abel. He was exchanged for U2
pilot Gary Powers.
The capture of Dick Hickock and Perry Smith is another
example.
They were the murders of the Clutter family in Kansas.
They were
also subjects of Truman Capote's book, In Cold Blood. Much of the data in the
files of the Department of Justice about the Cosa Nostra
