If you were in the security forces, then you would know how to track an Ip Address, the first thing I learned in the Armed Forces is how to do that,

You would also know that all connections in the UK go through 2 computers, which is constantly monitered for security reasons (won't tell you where, you should know)
You should also be aware that you can browse the person your getting your film from you can get their Ip address, then you can track them back, to where they are.
One other thing, You should also know that your ISP can retrace every move you made on the Internet, every site, IP address, exct

Now If you were in the security forces you should know this

By the way 5220.25M, is a pile of rubbish, all it does really is gets rid of the stuff out of the recycle bin, and deletes the top of the file (It is not meant to secure the hard drive)
And as you should also know No file that has been deleted can not be recovered, even using Military software, we were told to open the hard drives, take out the disks, and burn them, or destroy them anyway possible
