There are people I know that I can recognize by the way they walk, so the idea is at least plausible. I think the main problem is/will be from using the analysis inappropriately. It's one thing to narrow down a city-sized population to a list of 50 people known to walk with a similar gait, and then follow up with other forms of investigation before drawing conclusions. It's another for a cop to look at the top match and go arrest that guy, as they've done more than once with facial recognition.
