About 17:45 I turned the TV on to the local CBS affiliate. They were showing a peaceful protest; probably 3 to 4 thousand people on the I-35W bridge at Washington Ave, maybe more; both sides of the freeway. Everyone (protesters and cops) were behaving themselves and the cops were staying way back (they were off camera.) Then a tanker truck (gasoline or milk, most likely) drove thru the crowd; drove kinda fast. Don't think he ran over anybody but pretty sure he ran over a bicycle and maybe hit a few people. Could have been *really* bad. The protesters mobbed the truck and it stopped. I think they pulled the driver out. Couldn't see what if anything happened to the driver. Cops were there in seconds and dispersed the crowd with pepper spray or something. Still no sign of the driver, looking at it from a helicopter camera. Seemed appropriate level of response. SWAT showed up with an armored vehicle but didn't do anything; show of force I guess. The news crew just broadcast it live from the helicopter and the live crew on the ground, without a whole lot of commentary and apologized for some of the language from the crowd (I didn't hear anything bad)
That's all I got. No commentary in this post, I consider it news.
