Europhobia: The database state is one step closer
Courtesy of the EU, and we’re now well on the way to bypassing the British parliament just as Blair and co planned (even if they did originally want the data to be stored for three years):
“An European Union parliament committee voted on Thursday to keep details of all EU-wide telephone calls and Internet use for six months to a year to help combat terrorism and serious crime.”

Much of the data you mention is already stored for at least 6 months. For us basic law enforcement types getting hold of the material means jumping through several hoops and taking due account of the Human Rights Act at all times.
I can see this changing very soon to make it much easier to get the material. It is not what material is held that is the problem, it’s who can see / use it.
