Microsoft COFEE, the Most Illegal Download
Downloading and using software intended for law enforcement use only is a really bad idea. Seriously.
Yep, it's all out there on the internet, but if you use it to grab private data from someone else's computer chances are you're in for a world of legal hurt. It's one of the few pieces of software I can think of where the subsequent use is more illegal than the act of downloading it.
