Re: How could the gov't know?
Kiwi, thank you and you are welcome.
As regards your laptop question, it's an interesting question and quite honestly one I had not considered.
However, having quickly thought about it, my instinct is that even I don't think the government could get away with twisting the law to that level to target you as a private person in order to get access to equipment you own.
However, I still have concerns about general communications networks operated by large companies and organisations because I do believe it's far easier to twist the telecommunications operator definitions I quoted above to cover them.
