Absolutely not. If you're wanting to get somebody into the national program, then it's a fiscal consideration in large part, because somebody has to pay the bill. For a local police agency, coast to coast, that is a concern. Aside from the national program, though, you have something less than that, and certainly the cost is not a factor. The primary concern, of course, is the safety of the witness, without question.
