From: Schneier on Security
A burglar was identified by his dance moves, captured on security cameras:
“The 16-year-old juvenile suspect is known for his ‘swag,’ or signature dance move,” Heyse said, “and [he] does it in the hallways at school.” Presumably, although the report doesn’t make it clear, a classmate or teacher saw the video, recognized the distinctive swag and notified authorities.
But is swag admissible to identify a defendant? Assuming it really is unique or distinctive — and it looks that way from the clip, but I’m no swag expert — I’d say yes.
