At the last Republican convention, videographers caught police falsifying their accounts of what protesters who were arrested were doing. The group who did that is one of the groups who were targeted by police while in a home and not anywhere near any protests. This was done to intimidate them into not documenting the protests for this convention.

I don't know if they managed to make it to the protests this time, but whether they did or not, I wouldn't be willing to believe anything the police are saying about what people were doing without videographic evidence to back it up. If the RNC and the police don't want people videotaping the protests, it's a sure bet the the police intended to engage once again in illegal tactics and to falsify their accounts of what happened.
