Yeah and he didn't push the little old store clerk.
I was accused of stealing once at Target, and I was PISSED.   "the cashier (an elderly woman who was new at her job) got confused and thinks she gave you change for $100 instead of change for a $10... do you mind stepping back inside while we investigate this?"
My blood was boiling.   "Pull the video.  Pull it now.  Get her over here, pull the video, and I want to see it now.  Charge me or apologize, and quickly".  If I wasn't with the wifey, I may have kept walking and made them tackle me for the false charge.  They gave me a sweet gift card for my trouble 

Turns out she was confused and they train them to panic/accuse when they cannot remember if they just handed out a pile of 1s versus 20s...   
Now, I'm just a normal, well-mannered old dude with buzzed head and fanny pack full of kindness... but try that on a kid, and I can see it escalating fast.
I dunno what this video shows... dunno if dude stole, don't care.  I"m just saying if someone accuses me, blocks my exit, and I'm innocent, yet it may get physical fast.
