It's rather naive apart from being ethically objectionable to assume that our investigators travel around the country with bags of money trying to bribe witnesses to lie on the witness stand. We just don't operate that way.

The original PATRIOT Act greatly increased our nation's ability to share intelligence information made better use of technology and provided terrorism investigators tools that have long been available in cases involving illegal drugs and organized crime.

The investigator should have a robust faith - and yet not believe.

An investigator starts research in a new field with faith a foggy idea and a few wild experiments. Eventually the interplay of negative and positive results guides the work. By the time the research is completed he or she knows how it should have been started and conducted.

Us investigators who went out into the field were faced on occasion with a lot of anger by people saying why has it taken you five or six year to come and see me?
