If you're wondering where the three junior high kids are in the last panel, they stepped conveniently to the side and are off-panel to the the viewer's left.
Much like the previous comic, I initially struggled with the dialogue on this one. Not because of what was being said, but who was going to say it. I initially had Justin attempt to explain what happened, but Justin would naturally be unsure of what to say and what not to say. Once I realized he didn't have to say anything specific given the spectators butting in, the comic wrote itself.
I debated whether to show the non-comic shop people George is referring to, but their silhouettes were visible in the second to last panel of Monday's comic, and there were plenty of them, so I decided not to worry about it.
The cop's sunglasses are meant to look like those stylish sunglasses that always seem to have some sort of mountain landscape being reflected on them. I find those to be hilarious and believe every member of law enforcement should wear them.
And yes, that includes prosecutors.
