I remembered watching that and thinking that it was apt.... but there's no damn way anyone gets access to all those different systems managed by different groups seamlessly. The bureaucracy involved would be immense, the various systems that can't talk to each other efficiently endless. I imagined all the overhead that would go into that and it hurt my brain ;)
A fun thought exercise to break the "can't do it" perspective. Imagine someone says they'll give you 10 million dollars to get it done, could you do it then?
I think the challenge is you don't know where the "runner" you're tracking is going and the variety of surveillance systems they tap into is a pretty big unknown.
Well, there's DEA's Special Operations Division (SOD). As I recall, they've done ~real-time busts of drug shipments. That is, from a cellular intercept in California to pulling over a semi on I95 for a broken taillight.
