On Monday near Fronton Texas, Border Patrol agents were seen on video taking fire from heavily armed persons suspected of being members of Mexican cartels. This fire was taken right as a group of migrants were attempting to enter the country illegally by crossing the Rio Grande.  Texas Department of Public Safety assisted with drone deployment, which captured footage of the gunmen attempting to retreat back to Mexico.  Only a single shot was returned at the Mexicans. Was it the opening to a much bigger and more violent about to explode on the border?
