doubt it...it was done before bank surveillance cameras at an ATM
Off topic but this reminds me of a story when I was in elementary school. As the day ends the Principal gets on the loudspeaker in a serious tone and explains a situation that a high school girl was slashed on her way home by a black man who is still on the loose, be very careful walking home. Flyers were given to us and mailed to homes, for a week every kid was scared of “The Slasher”, turned out the girl slashed herself, made the story up, and was arrested.
As you said this is probably true and one would think a normal human being would not slash themself but crazier things have happened.
