Just to clarify...there are lots of ways to skin a dawg, many ways to hack, track, and gather info etc. It's complicated,, and my response was to the original premise...can the FBI be shown a video, and track down the user based upon IP address. Technically yes....in reality...no. They can only ask someone like me to do it for them....still VERY difficult and time consuming...it ain't TV
. I was a communications systems programmer (370 Assembler) and networking guru with high end advanced communications devices (500k+), protocols, etc. debugging, traces and figuring stuff out was my career. Started my career in IBM's Advanced Communications Products Division....microcode dvelopment at RTP....fun times for sure....now part of Cisco.
