Francisco Erwin Galicia was held 23 days incommunicado by CBP in Texas. Was he arrested or detained? What is the line of reasoning for arriving at the conclusion?
Update: Galacia's attorney indicated a notice from DHS:
The notice reads, “On or about June 27, 2019, you were found at the Falfurrias, Texas, Border Patrol Checkpoint, a distance of more than 25 miles from the United States border with Mexico ... You did not receive the permission of an immigration officer to proceed beyond that 25 mile limit ... At that time, you falsely represented yourself to be a citizen of the United States for the purpose of furthering your entry into the United States.”
