what's changing?
This may result in a change to what happens in courts, but probably not what happens on the net. IP addresses aren't guaranteed to lead to a person. Many people use VPNs in different countries from where they are located. Without knowing the specific person, there simply is no knowing where they are. This leads me to think that these FBI law scoffers enforcers have been happily hacking into people's computers all over the world already.
