My info is dated, back in the day when LI was passed became federal law, I working in telecom and we had to have LI ports on all backbone ISP routers. No idea what legal process they had there, but operations didn't touch the LI ports. I heard it had a federal portal that the feds could access directly.
This was almost 2 decades ago, but on mobiles, they had a custom portal where you put in a phone number, and all traffic is logged, location, etc. Also they had a department to handle just warrants for data for mobiles.
This is almost the same way we did for child porn cases about 10 years later in photo hosting. Either a photo matched a known md5 sum of content, or a cop would submit a warrant, legal would contact operations and ask us to run the warrant script. The script would zip up the entire user's data and burn to dvd. The cop would walk into the data center and pick it up.
No chain of custody would include an employee. I'm assuming facebook/twitter has portals for feds now, since they already have government portals for cities/state employees.
