Hands up. Don't shoot. Hands up.Police say the protest ended with no injuries, shootings or property damage.At one point, though, the St. Louis County Police Department tweeted, this is no longer a peaceful protest.They have a right to be mad. We all have a right to be mad, and we have a right to say whatever.Thirty-two-year-old Rnesha Baldwin lives in St. Louis and said she's been coming to protests here since last August.Last night escalated because, she said, police overreacted.So if they stand there and they didn't respond and didn't say anything, everything would've stayed chill and peaceful.Police said, though, that they were responding to participants who threw bottles and rocks at them.The city was already on edge after shootings and store lootings over the weekend.On Monday before the protest, Ferguson resident Lavonda Logan said it's starting to look like August 2014 all over again.
