I have a different view. When I look at the function of the bill, I see that obviously the portions included in part 2, to which I assume you're referring, exist so that part 1 may function. When you look at what can actually be requested under part 1, you see that you first have the connection between a particular number, an IP address, or a phone number to a service and the subscriber information. To me, having this information available is akin to what used to be published in the phone book, and allowing cops to access a modern version of that tool to help them bust crime is just a good idea.
