I don't even understand the concern here. Perhaps the parent thought this meant "a warrant is not required", which is absolutely untrue. Instead, the judge still creates the warrant, and any trial/arrest/action must have a warrant.
(Finding out what ISP a user belongs to, isn't really that private. If you look at the US comparatively, Homeland has a list of every single credit card transaction ever. The US doesn't need to ask an ISP if someone is a customer. What this does is simply confirm, and then the judge can create a warrant specific for that ISP.)
Such as compelling the ISP, or what not, to take action. The ISP is not the subject here. And obviously hiding the warrant from the ISP makes zero sense, as they're going to know who the person is anyhow.
This is stuff that goes back to phone taps. Nothing new here.
Does a warrant ever expire? How long can they monitor you once the warrant is issued? Do they ever have to notify you or anyone else that you were being monitored and they found no criminal conduct? Don't you see the potential for abuse here?
