The Federal Government seeks to change the rules to obtain warrants automatically against anyone using VPN or Tor -- because these are means of hiding the location of a computer.
If the current law says that you need to be in the targets jurisdiction to obtain a warrant, and you can't find the target's location because they are obscuring it via a VPN or Tor, doesn't it make sense that the government should be able to get a warrant in the jurisdiction where the crime was committed?
Can you link to the part that is changes to "broad sweeping authority"?
