I just checked the comments after the you tube video and the oldest one was 22 hours ago so it had to be shot earlier yesterday.
Still photograpsh that have not had the EXIF DATA scrubbed can be checked for Date...Time...and hundreds of photo equipment and setting specific data “points”
sadly I dont think that the files on youtube have such data embedded in them
Maybe the video is of them leaving. They pulled off of Bundy’s ranch on Saturday but regrouped near the Utah border around Mesquite, IIRC.
