Here's how I would handle it:

In addition to calling several high profile agencies like ACLU and EFF, I would call one or two local lawyers and say,

"Hi, my name is FirstLast, at 2:05 PM I was at LAX Terminal 2. A man wearing XYZ was being led away by CBP agents and was pleading for someone to call a lawyer. Is this something you can handle? I imagine you can get in contact with LAX authorities if you are interested in taking this case."

I guess it's different at the federal level because they can detain people longer and with less cause, but eventually I believe they have to be offered the right to legal representation and being hauled in front of a judge publically.

Unless of course the US Govt wants to extradite you from LAX to Guantanamo, at which point a lawyer is the least of your worries.
