To those dismissing illegal acts from the protesters I will leave you with a reality check: If the police tell you that you have violated a law and vacate the area, you vacate the area. Failure to follow police commands ends in one of three possibilities 1) you get arrested 2) you get your ass kicked by the police 3) all of the above. The police have a job to do, that is enforce the law and it does not allow for whatever the hell you think passes as moral superiority(hint: You probably don't know what the hell is going on anyway or you would have taken a different route to begin with).
Next, your ideas do not make you immune to getting your ass kicked by the police and it doesn't dismiss charges......if you remain after a police warning you are wrong, you were actually wrong to begin with which is why you were warned to begin with. Pepper/freeze spray hurts, it's supposed to in order to either surpress the very stupid move of charging at or throwing objects towards police.....we'll call it anti-dummy spray. Less than lethal methods of crowd control such as tear gas, bean bag rounds, and rubber bullets are par for the course when you decide to try and riot, they hurt, they injure, they are supposed to but you complain that they hurt and you know what, we don't care because if you had done what you were told to begin with guess what.....they DON'T get used.....gasp.
Finally, if you had been in a less free country it wouldn't be simple injury you would be complaining about because they would have used real bullets, chlorine gas, or military vehicles to clear you out, that isn't simple injury......that's DEAD. So maybe.....just maybe stop whining because you are wrong, very wrong, and if you hadn't gone over your freedom of speech line you wouldn't be bleeding.
Have a nice day.
