Tear Gas used on peaceful protestors tonight. We rushed a young African American man to West Penn Hospital ironically enough with a police escort. He was on the corner of Penn and Highland having a seizure or heart attack after being tear-gassed. He could not talk for he was in so much pain. We think his name is Sean Greene. He's in his twenties, about 5'7", thin, slight beard, wearing black canvas ankle-high shoes, black Adidas pants, grey/white striped shirt, and a black scarf. Please spread the word to find this young man's family!
