It's true, that shit sucks. However, the protesters were blocking the street. Peaceful or not, that immediately allows the police to use necessary force to clear the area. Now, if she had been in a field or on the sidewalk or something of that nature, and thats where the protest actually was, this would be inexcusable. I DONT agree with the laughing though, that's fucked up. Being a cop isn't about fun, it's about protecting and serving.
Peace is a lie. Freedom is a lie. Most everything you think you know is a lie. Get used to it. Get funkified instead.
