Having ISPs police the net has serious problems which all Government seem to be blissfully unaware of.
Just think (if you are using Wi-Fi) as you are reading this comment your computer could be easily accessed from a car or a neighbor in your street and it could be downloading illegal material for which you could be fined or imprisoned depending on the content of the download.
This brings me to say that the Laws as to downloading martial as they are cannot be seriously enforced, as anyone could have placed this material on you ISP’s server track record (and or on your computer’s hard drive) simply by carrying out the latter.
As to encryption of your ‘Wi-Fi Security System’ there are devices that can decrypt any encryption in a matter of minutes sometimes-even seconds.
Remember the pub owner in UK (under Mandy's revised Law) was fined £8000 when one of his customers was caught downloading copyrighted digital content from the pub’s Wi-Fi See ‘Digital Rights Act/ Digital Economy Bill’ is legally seriously flawed. http://tinyurl.com/y9nfdga
It is possible that I have discovered a Gaping Hole in Anti Piracy Copyright Laws.
The reason being that Copyrights strength is in the fact that it is ‘Legally Regarded’ as if written in stone whatever material is under copyright. Hence if you only copy a segment of the original Copyright material it is not theft as it is incomplete. Hence not as the original as the original is a completed script hence taking a single element cannot be judged as Copyright Theft.
Likewise if you copy Copyright Text and change the font it is not as the original yet by changing the wording of text slightly puts you well safe of being charged with copyright theft.
