Kops have shut the Morrison Bridge down. tons of all different kinds are all over the place, closing many blocks downtown.
All the folks at SW 4th and Stark who were sitting in the intersection are believed to have been arrested (corporate news coverage seems to confirm this-- face down and cuffed)
This caller has seen 10 or so people arrested so far, has not heard bullets fired at all.
The situation seems to be deescalating.
