UK hacker - now where did he hack?

The case against the UK hacker GARY MCKINNON who broke into various US military, NASA etc computer systems has been published (he was convinced the US were covering up alien landings etc and wanted to find proof, unfortunately he didn't just peek around, but messed with the systems).

There's a PDF of the case at findalaw. The document has all the IP addresses of the hacked systems blacked out.

However open the document in Acrobat, select all, and copy into your favourite text editor .... lo and behold the black marks have disappeared revealing the orginal text (i.e. IP addresses).

No wonder the US government is worried about hackers ... doh
