"Seeing friends get carted out of there like that hurt," Michael P. Whiter, a pot activist who attended the event, shared on Facebook. Whiter added that he's trying to deal with the situation "rationally and not emotionally."
As of early Sunday morning, police haven't released any information about the raid, including the number of people detained and arrested.
Among those detained by police was Philly.com columnist Chris Goldstein, who tweeted about the raid as it was happening.
"I was invited by Poe to check out the party, and I was planning on writing about it at some point," Fiorillo wrote. "Just not like this."
