The BBC apparently analyzed the footage and identified the subject as Alex Pretti, who was shot and killed last week during a confrontation with the Border Patrol. Pretti allegedly scrubbed his social media presence one day prior to his actions leading to his death. His parents had said he'd quit his job as an ICE nurse months ago and had shown signs of "unusual behavior." Reports also say that Pretti legally owned the gun he was carrying, but didn't have ID or his carry permit with him. Alex Pretti doing everything on camera except "legal observing."
