Indeed - and also, if you do assume the gov't is interested in your usernames, passwords and browsing habits (which appeared to be a concern earlier in the thread) and was involved in this conspiracy .. there are much easier ways they could get the data than relying on Google driving past your house and hoping that the people they're interested in happen to have an unsecured WiFi router

Considering there are actually relatively few points, for example, that you would need to monitor to see all communications into & out of the country..
Or that a great many people quite happily send their email account passwords unencrypted over the Internet at large (e.g. if you log in to your webmail on http:// rather than https://, or if you use the default POP3/IMAP configurations rather than IMAPS), or use the same passwords for their IM as their email as their bank etc..
If you're that paranoid about security, you probably shouldn't be on the internet in the first place

(or all of your traffic should be encrypted point-to-point, tunnelled over a VPN that emerges out of a foreign country and using something like TOR - all of which would make your browsing experience something like using a 9600baud modem, of course
