The answer is, as I've experienced it, NO. The subject is not meant to be inflamitory, but reflects the horrible experience I've had in just this item. The police don't typically know what the hell a computer is, what a "compromised" system means, and so on. Okay ... I see this is going to need some explaining:

In another forum, I talked about my experiences with crackers from the .cz (czhekoslovakia) domain. We had them nailed cold, down to a couple of IP addresses (sure, they could be spoofed ... but all you can really do is trace as far back as you can and go from there). The boxes were spooled to tape, and we were starting forensics on the boxes involved. We called the police in to get a report number, and the guy that they sent didn't know too much of anything - it was like, "so ... you mean, these guys from overseas can talk to this box through this wire-thingy? Woooooowwww ... <dummy mode on>". We started looking into getting the FBI involved, but they won't even come out until $400K damage has been caused.

Here's the breakdown:
Are we ready? No.
Until there exists crack teams in many metro PD's, we're not going to see this improve. Here's why - as an ISP, you obviously want to get the legal system (i.e. Government) involved in anything that is pretty large and international. However, the groups who *do* know what they're doing (NSA, FBI Cybercrime unit, CIA) typically don't like to talk with each other (like the old MI5-MI6 problems, too) and are busy chasing shadows as it is. So as an ISP the only reasonable state-side resource is the police. Who typically don't have a cybercrime unit. So the only thing that an ISP can really do is complain upstream until it comes to, say, AT&T talking to CZ.net or whoever. And at this point, it's been my experience that a lot of companies are simply too big, too slow, and too "busy" to persue the matter with the persistance that it needs.

Hopefully this gives some insight.

PS: The U.S. is vulnerable to a whole lot. Computer-crime, box-cutters, zero-tolerence weapons policies at schools gone haywire ... and so on.
