Mark opened a Friday show with a four-story lineup, but the source material only develops the first: gunfire on the Rio Grande. A Coast Guard crew on a joint interdiction patrol near Garceno, Texas, took fire from the Mexican side last Saturday and returned it, with no injuries reported, and Army troops from West Texas are expected to stage in the Rio Grande Valley for at least thirty days, with size and mission undisclosed. He walked through a record of similar incidents since 2014, including Texas game wardens, a state trooper hit by a stray round, and Border Patrol agents fired on from the ground, and argued that cartels act as if the river is theirs because the consequences have been so small. The rest of the lineup was previewed only briefly: a weak September jobs report of 29,000 added jobs against 85,000 expected, a G7 oil release that may barely move pump prices, and the Army's new Futures and Autonomous Systems Command for robot warfare.
