How do you know this. You are making assumptions and you really are not looking at the complexity of the entire event. How many cops do you need for a protest you do not know the size of the crowd until it gets there. You have no clue who is coming from out of state and you still need police to do their normal jobs around the city. Where are you getting your data they have sufficient personnel or is this just a guess. Also when an incident breaks out in one part of a protest, how many cops will be needed for that. How many cops are needed for the direct conflicts where both opposing sides are right next to each other. It seems you have this simplistic view of the situation without really thinking about the complexity especially since it's not a stationary event. With incidents happening throughout the city, you believe that ever inch will have a police there to cover such a large area, that sounds very naive.
Lol, that's all the cops have to do is stop people from getting seriously hurt. Man you must be very young because your statement is something out of some idealistic view with totally no experience in history. This is why people find themselves at these protest getting stomped believing as you do. Oh, well, at the end of the day, I suggest you never find yourself out on the street proclaiming your right to protest hoping their will be enough police in the area to make sure you do not get hurt.
Lol i'm having an idealistic view by expecting the police to do their job properly? Whatever dude you keep defending them. I feel sorry for you that you don't hold cops to a higher degree.
