Sci & Tech of Future Crime

Greetings,

I was pondering the (un)likelyhood of space piracy the other day, and
it got me thinking about other futuristic crimes. Things like identity
theft, computer crime and related malfeasance are fairly easy to
extrapolate. What I was more curious about is blue-collar, street-
level crime. I Don't have a specific question, per se, but I have
listed a few discussion seeds below:

1) How does the morally flexible entrepreneur of the future pay his
suppliers/receive payment from his clients? Obviously credit cards
and other electronic transactions are out, as they are too easily
tracked. Usually such types use cash, but in a world where RFID
technology is dirt cheap, it is easy to imagine every bill printed
(assuming bills are even still used) having an implanted RFID-like
chip.

2) Obviously, we don't solve as many murders as we'd like today, but
we are getting better at it. In a future with handheld chemical
scanners/analyzers and various other advanced analytical tools, does
murder become impractical as a premeditated crime?

3) How likely is space piracy? Given that stealth is just about
impossible in space, it seems improbable that a pirate corsair is
going to 'jump' your freighter. Seems the most likely scenario is some
sort of elaborate inside job, but even then, how do you hide the
megafreighter you just stole?

4) Will T-ray scanners and advanced image recognition software make
smuggling of any kind completely impossible?

I know this is largely a physics-oriented board, so forgive me if this
strays too far from the path.
