Virtually no cafe's (by which I mean I know of none and have heard of none) do what the Police are asking in your first link. It is completely optional, and indeed may break other laws such as the Data Protection Act if not done properly and with notice to the user.

With regards to the second link, that law is a fair way off and already faces quite stiff opposition. Similar but less intrusive laws already in place which require ISPs to retain certain logs if requested have not yet proved too onerous (and have not been abused on a large scale), and certainly don't interfere directly with most peoples use of the net, at home or in public spaces like internet cafes. This isn't to say that I support the existing laws, I don't, but they are in no way of the same type, scale or intrusiveness as the situation described in the article.
