>If you want to buy a botnet, it'll cost you somewhere in the region of $700
>ZeuS source code: $200-$500
Nope, total bullshit. It is widely available. 
>SOCKS bot (to get around firewalls): $100
Nope. "Socks bot" refers to the ability to convert an infected computer into a SOCKSv5 proxy
>Unintelligent exploit bundle: $25
This refers to exploit packs, which is obfuscated software sold on these boards that contain unpatched 0day exploits. Exploit packs are worthless after a week, unless updated since all the vulnerabilities (apart from Java). They're available for free.
On top of that, the excerpt of Germany's most basic collection of laws you have linked () just states that there will be no extradiction to US. This only means that people will be punished for their crimes within Germany and not in the U.S. - but not that they won't be punished at all.
