They're also tools of the offense, which means that they're used to commit some traditional offense. In the old days, tellers used to take money from the till and stick it in their pocket. Now they write little programs to syphon off pennies from accounts and funnel it into another account, the so-called salami technique. You take thin slices off a big chunk. And then we see computers what we call incidental to the offenses, which means they're not directly involved in the offense, but they're important to law enforcement.
Drug dealers are an example.
In the old days, we'd get a search warrant, kick in the door, and if we did our job right, there would be white powder and currency and a little black book. And you opened up that little black book and you find names, dates and amounts. And the reason that this is so significant to law enforcement is any federal agent can open up that black book, but I have to tell you not every federal agent should be turning on that computer. It could be that he's simply unaware of the programs that are running, the operations software. Maybe he knows Excel and it's running Lotus.
