I think old man staged his being a victim for the cameras and got more than he bargained for. Whether the police caused the fall or the man faked it really is a different issue.
Faked what? Bleeding from his head?
Why is the old geezer any different from the hundreds of other protesters who have directly confronted the police?
Have you seen the video? A cop bush the old man. The old man fell backwards and hit the back of his head on the sidewalk. We see him bleeding on the sidewalk as the police walk away. One cop apparently called for assistance. End of story.
Is there any part of the video you don't understand?
Supporting Trump on this issue is really dumb. GOP leaders in Congress want nothing to do with the mindless tweet. You should follow suit.
