@msolga,
I read a lot and came across the information/claimed that 400,000 plus cases of banks and isp records and other information was accessed by the UK government in the last ten years using the power of their 2001 anti-terrorism law.
I had not been able to re-find the 400,000 figure for some reason using google however the act is on the book and does give the UK government that kind of power.
Once more it would seems that if they<uk governmet> care to look at facebook and similar information they could do so with no block of any kind for doing so in relationship to wikileaks investigations.
Such records on the whole are going to be open to governments and anyone annoying governments to the degree that the wikileaks people had done should not be shock at that fact.
Footnote for some reason the US ask for information not using our terrorism act and that how it ended up in court but the US terrorism act even forbid anyone that turn over such information from telling anyone they had done so.
