At the Republican convention, demonstrators are acting a bit crazy. Sometimes, its best for the police to just step back and let them at each other.
"It's the largest gathering of protest groups and the largest gathering of police since the beginning of the Republican National Convention.
Activists from Black Lives Matter, Westboro Baptist Church and the KKK were in the square and, at one time, were said to be throwing urine at each other.
Police were trying to draw a line and keep the groups separated. A police spokeswoman said that emotions were high, but not too many fights broke out."
