Re: Disproportionate? Let's see. 200 protesters charged. 1.3 IP addresses wanted.
Isn't that rather the point... If they do have a suspect's IP list then let them present it to the ISPs for matching/data extraction, and not the way they're trying to fish it?
Why is the ISP being asked to justify its refusal - the requestor should be justifying its request - hook line and sinker.
