Warrants are SUPPOSED to be difficult to obtain.
The cops have been doing their jobs just fine arresting criminals since before the days of Jesse James without any ID.
They didn't even have any ID at all back then.
Warrants are not supposed to be impossible. If you cannot ID a person in todays world you cannot gain a warrant. But then, that is what you really seek huh?
I will ask you too and a bit more specific this time.
How can one gain a warrant in today's world without establishing the identity of the person one seeks to gain a warrant against?
