Innocent until proven guilty - they cannot simply say "we think you downloaded music, have a fine" unless they can prove your connection was used, by you, with one of your machines. This is why Police sieze the machines when they have suspicion of fraud, child porn, etc... they cannot convict without proof that the material is on the machine.

So far, the BPI dont have that power, and the Police have better things to do than waste resources on such matters. The RIAA have been spitting out subpoenas for peoples hard disks for just this reason - but that is the US, not here.
