Bobby Daggett of Portland, dressed as Green Lantern, said he witnessed the first assault.
"There were a bunch of people standing outside trying to drum up business and one guy was dressed as a Stormtrooper," said Daggett. "Out of nowhere this guy tried to put [the guy in the Stormtrooper costume] in a chokehold from behind and then throws him to the ground. He was trying to be intimidating above him and screamed obscenities to everybody."
Barnes had walked across the street to commit the assault, Daggett said.
"Why would somebody just decide to go well out of their way to do it?" Daggett asked.
Barnes was confronted by police a block away.
"He was taunting and challenging police officers and then he got Tased," said [Police Lieutenant Gary] Hutcheson.
"I've been a cop for 23 years, I've never heard of a Ghostbuster and a Stormtrooper getting assaulted," he said.
I dunno, maybe dude just hates cosplayers. Or maybe he hates comic books because they have so many big words in them. I imagine, when you get right down to it though, dude's just a bully. I can always smell a bully. You smell it too? "Smells like shit." That's it -- that's the smell!
