Who needs facial recognition if you can identify people based on gait?

Gait recognition is almost entirely hype. Sure it works to tell the difference between n = 10 people but so what, you can tell the difference between a group of 10 people by what kind of shoes they are wearing.

Judicial systems where a 6% error rate is deemed way too high to lead to a conviction.

		Then you combine it with some other technique, eg tracking daily routes of individuals, to lower the error rate. You only need a handful of bits to distinguish all inhabitants of the average city. But imho that error rate would likely be low enough for some judge to authorize more invasive surveillance of suspects thus identified.
