I work across the street from the Manns Chinese Theatre in Hollywood. There are countless tourists, and a few dozen costumed performers posing in photos for tips with them.
They just arrested Spider-Man. It took five cops to bring him down, but he was publically unmasked, and shoved in a police car. They're presently questioning Spongebob on the scene.
I am totally kicking myself for not carrying a camera wherever I go, but like I said, there are countless tourists onhand to fill that void. Watch for pictures popping up online in the next hour or two.
"This looks like a job for the CBLDF!" might have been a better title. Didn't think of it. Sue me.
No sign of the arrest on google yet, but I did find this. And this.
