Most people dont know the technology out there. Like you said. they literally have scouts. They have got people every so often. every so many yards or 100 yards. whatever the distance. spotting where the Border Patrol agents are. They know everything about these Border Patrol agents. I heard a story that one of the people crossing the border actually had a booklet with all the names. addresses. and the tendencies of each and every Border Patrol agent. They knew if they chewed gum. if they chewed tobacco. if they read a book while they were sitting there. They knew how slow they drove from checkpoint to checkpoint.
Identified stereotypes
Generalization that people crossing the border are organized, technologically savvy, and know details about Border Patrol agents.
