Most Helpful Girl
There's no one else in the picture, and there are no other obvious clues to the weather. The weather is VERY important here.
IF IT'S BELOW FREEZING:
• Newly homeless
• Blue-collar and active (moves around too much for a thicker coat)
IF IT'S COOL, BUT NOT FREEZING:
• "Urban survivalist" type (like @anonman32 said)
• Outdoor worker/outdoorsman who's wearing 4 different layers under that jacket
IF IT'S WARM OUTSIDE:
• Thief or pickpocket, with many convenient places to conceal stolen goods -- and weapons.
(Could be this if it's not warm out, too... but, if it IS warm out, this is the *only* reason why someone would dress like this.)0

They guy looks crazy. Maybe homeless but i've never seen a hobo with a knife like that and with a tucked in shirt.
Maybe a time traveler from a dystopian future where civilization had collapsed.
I certainly wouldn't approach the guy.
All joking aside, Is this guy an actor on a movie set or something.0
