The third photo’s “some sort of sharp object” is a recurve bow with a nocked arrow - and the bowstring improperly strung.
I suspect that police recognized it and are just playing dumb with the caption so whomever was in the photo can’t get in trouble for having a weapon in the area.
Good eye!
Obviously a member of the Old Folks home clandestine deer jacklighting team. (grandma division).
The third photo is an old lady with a walker, holding onto reins.......
