You know, it could have been me that published first on this, and maybe got credit for "the kill", but by the time I spent a night pondering the ethics of spilling a guy's Facebook pictures, they were already MSM fodder and British Columbia New Democratic candidate Ray Lam had already stepped down.
Clearly one of Mr. Lam's Facebook friends was a political opponent, or alternatively Mr. Lam had a falling out with one of his real friends, and hey presto "private" pictures became public.
It is quite common, by the way, to sign up as a Facebook friend of some politician/potential candidate and hope they 1) post pictures of themselves in their underwear or 2) become associated with radical types. Facebook encourages shoddy screening processes, because your cred there is a function of the number of friends you have. I, for example, have so few friends that I will accept pretty much anyone. Mind you, I don't intend to run for public office.
Gary Wise has done a fine series of posts on your Facebook privacy rights and other topics re the Facebook social networking phenomenon. David Canton covers similar ground in today's LFP (and, as a free bonus, talks a little about the FreeD case). In short, however, your privacy rights on a social networking site are probably less than you thought.
