enforcement respond to this awful situation? >> caller: i honestly say that law enforcement were prompt. they are usually down there with heavy presence on saturdays in the oregon district. it's usually peaceful because of it. but at that point, they responded quickly. i can't say what i seen any of them do. i was kind of running. i know for sure that they got him down in at least within a minute or it wasn't too long. >> anthony, did you see the shooter? >> yes. heavy-set white man, black attire. he had a face covering up. you could see the top of his head. >> did he say anything? was there any warning? >> no. didn't hear any warning. it was nothing. you really can't hear anything because there's bands outside sometimes playing music. you got people.
