Police in Charlottesville didn't enter the fray right away because the chief was afraid that the troops would get lost among the crowd and lose touch with one another. This is significant because had police entered the arena sooner, maybe as soon as things began, the violence may not have swelled to the point that it did. I can see the chief's point too, not wanting to lose touch with your force and perhaps some being wounded or killed, certainly would have added more confusion and anger to the day. The article also states that the protesters had said that they were going to enter the park from a certain point only and instead came in from every angle. I can understand how this would have thrown the force off balance too. I have to ask myself though, "why would you trust a group like this to do what they say they're going to do?" Obviously there was no way of knowing how bad things would get so they couldn't have brought in the National Guard "just in case." Or could they have done? Historically many of these sorts of protests turn violent. I don't pretend to understand the workings of government, but in my mind a bigger show of force from the beginning may well have kept things under control. I do not in any way mean to minimize the injuries and losses experienced by people that took a stand, I hope it doesn't come across that way.
