We have a lot of police in this country and there is an approval process for these protests so they are informed beforehand about it and they should do a better job at being more prepared. This isn't their first protest so they can come up with a good estimate on the amount of participants bad on other protest.
Jason you are being very naive about this. Yes, the protest which was the conservatives can be approved. What is stopping the other people which was Antifa from coming. There is no approval process for them and there is no way to know how many were going to show up and counter protest. Its as if you are only looking at half the problem and not thinking about the total issue. Anyone can just show up to these protest and there is no way to totally prepare or being in multiple places at once for already shorthand amount of Police.
You are correct this isn't the first rodeo and the problem remains the same, not enough police for the area to police. So what should happen is they deny any protest period and they would not have to worry about the issue at all.
