Because they work?
Because some of them are criminals too and fear being stumbled over in an investigation?
Because they are on the side of the bad guys?

What’s your take?

"Roving wiretaps have been used for decades by law enforcement in routine narcotics cases. They reportedly were used to help thwart a plot earlier this year to blow up synagogues in Riverdale, N.Y.

The value of lone wolf authority is best demonstrated by its absence in the summer of 2001. That's when FBI agents might have obtained a warrant to search the computer of Zacharias Moussaoui, often referred to as the "20th hijacker," before the 9/11 attacks—although there was no proof at the time of his arrest on an immigration violation that he was acting for a terrorist organization. But a later search of his computer revealed just that.
