I share the view that there are people you meet first time, passing, etc, and your internal bell just rings for no apparent reason (sometimes quiet, but persistent, background noise to be weary). On one hand, I'd love to see research into this and intuition as well, on the other hand, re. research results, I hear this quiet, but persistent, background noise that tells me the outcome won't be used for anything good.
As to mugshots shown on media though, I'd be VERY careful. Whoever is paraded for a mugshot opportunity, they won't be in a good mood, and our own bias tells us that they must be bad, bad people. And even if they grin stupidly (because one moment they were having a good night's sleep, the next they found themselves in a police cell and what the f... just happened?!) to us they're not just bad, they're evil monster with an evil grin, etc. Media illustrate text with a shot that is put there to reinforce the message, which is manipulation, but there's hardly any news that isn't.
