Look, we'd get strange phone numbers on our bills and I'd call the party on the other end and find out who they were and who it was hacked our numbers to call them.

Send that sucker over to the cops and make a collection.

Theoretically the cops would need a warrant to make that call to whoever it was at the other end. Remember, they'd "done nothing".

I didn't need a warrant.

No one ever questioned this method, least of all the phone company.

It's like this, phones are not new. Phone scams have been around a long time. If you're getting billed for someone else's "use" you are allowed to pursue them!

what does your reply have to do with the question as to whether the list of numbers you call belongs to you, and requires a warrant for the gov't to obtain?
