Think thats scary look up gait recognition. I remember reading a book in middle school almost 20 years ago, in the book they used gait recognition because facial recognition was deemed to invasive and was made illegal. Probably based on real life but I never looked into the legality of it. The original Punisher show on Netflix also brought it up, its how the hacker dude finds Frank Castle and kicks off the shows plot.

There’s an abductee account from the 70s or 80s where a logger claims he saw a craft when he was out in the woods and when he approached it, it blasted him back with some kind of energy blast. He disappeared for a few days and when he showed up again he claimed that aliens abducted him and repaired any damage they did to him and just dropped him back off. Dont think he got a steak dinner out of it but the whole account was interesting to me and corroborated by a few of his coworkers he was with when it happened. Name’s Travis Walton if anyone is also interested.
