First, to put the "biker" thing in perspective, let me say that I spent 20 years riding bikes - go-fast to touring bikes - and met a number of Harley riders who were simply rough gentlemen. My wife and I also took a Motorcycle Safety Foundation class and happened to be in the same class as
Ralph "Sonny" Barger of
Hells Angel's infamy and his wife Sharon. For all that's been written about Sonny, he was an absolute gentleman to everyone in the class and the biggest supporter of the most novice rider. If you met the man not wearing "biker" clothes, you'd think he was in construction or similar blue collar line.
This only illustrates that clothing and demeanor don't always tell you about the person's true character.

Looking for a criminal is a bad idea. Look at everyone. Look at their pants, shirt, shoes, hands, face, hat, gender, eyes, way they walk and their level of alertness. Do a play by play like them guys on the glow box when football is on.
[Warning: I'm going to use some stereotypes and rude characterizations in the following, only to make a point.]
In a sense, yes. But by scanning over a group of people you mentally "dismiss" various types. For instance, if you're walking in/out of Wally World for your cheap 9mm ammo, you dismiss the
Waddling Welfare Whales as well as the almost any "breeder" family group with a passle of young kids. The ones who look like grandparents aren't likely to pose a high risk and you can dismiss most fortyish looking males pushing a shopping cart.
Even the teens dressed in baggy clothes can be rendered a low risk if you see them accompanying their parents and younger siblings.
On the other hand, younger males between about 15 and 30 who don't seem to be purposefully heading into the store or who appear to be leaving the storefront without any purchases
are suspicious to me.
A lone individual who seems to be paying a lot of attention to people walking by or keeps looking into the store as if to see the activity inside, gets my attention. Glancing around quickly is another red flag.
A group of younger people - who may be mixed genders - if they are "hanging out", dressed in similar styles and colors, that sets off my radar. And if several happen to look your way at about the same time, the boatswain's whistle goes off to set condition orange.
In public venues I tend to look at faces, body language and hands.
Faces - sometimes you can tell the shopper or average joe from the ones with intent to do something. Quick head movements, darting eyes, tense jaws signal a higher emotional state than your average person. Wild, wide open eyes may be a signal of an impending attack (or a desperate search for a restroom or lost child). Flaring nostrils (to breathe more) indicate an elevated risk of attack.
Body Language - their gait, shoulder position, speed of movement can all indicate someone moving purposefully or with assertiveness. In a crowded mall, someone hurrying to a shop may walk quickly, blading their body through the crowd. Someone trying to flee without running will drop their leading shoulder as if ready to "block" or shove someone out of the way. In a less crowded mall, someone walking briskly but on the balls of their feet like a prizefighter is likely closing in on their selected victim, espeically if they're not looking for, or taking, less resistive paths.
Hands - Hands will hurt you. Specifically, fists and objects held in the hands will hurt you.
Where are his hands? What's in his hands? Because the bag he has doesn't look big or heavy, doesn't mean it can't be used as a distraction tool. If you can't see both hands be prepared to act quickly.
