Sad day
When people condone the highly illegal breaches of every data protection law we have, just because they disagree with a political stance.
This was marked as being an 'inside job', which means someone authorised to have the info simply walked off with it. It's not a security breach in "an external cracker got into our systems and lifted it".. It's a case of someone who was put in a position of trust decided to breach that trust.
Whatever the rationale, if that person is discovered, they should NEVER work in a sensitive data environment ever again. If you disagree with something, by all means, walk out, but don't screw over your organisation, and all the affiliates.
As to Jacqui Smith saying that she didn't mind people knowing she was a member of the Labour Party, would she mind everyone knowing her home address(es), email and telephone number? Her kids' details, and the rest of her family info? Don't think that would fly somehow.
Personally, I find it weird that you can be a member of a hard left organisation with nobody batting an eyelid, yet join a hard right, and you're automatically evil (both sides are pretty much nasty). And having non-terror parties on a membership blacklist for certain professions?
As long as it doesn't influence their day to day job then why the hell do people care (apart from creating a bogeyman for everyone to 'fear' and be 'protected from').
And of course 'respected members of the community' keep quiet largely about BNP membership. Everything that's ever said about it is in vilification. As soon as that's brought up, anything else someone may have done is automatically ignored, and that membership becomes the be all and end all; this is about the only political party I know of that this happens with. So much for freedom of political expression!
I don't really agree with the BNP (being very much middle of the road), but hey.. Just because I strongly disagree with their policy shouldn't mean I have an automatic right to censor them. And I certainly don't have the right to expose their details to their absolute extreme opposites, many of who will almost certainly not be above the use of violence and directed hate campaigns.
So, if anything, this release if details is pretty much an incitement to the commitment of hate crimes. Which is a Bad Thing(TM). Worse than the BNPs homegrown bigotry.
