Anonymizing photos of the violent ones is therefore likely to support their actions by making accountability less likely. To scrub ethically, limit it to the non-violent protestors. To support non-violence, better to help identify the violent people -- police or civilian -- the opposite of anonymizing them.
In a situation where police feel justified to kill extra-judicially over a possibly fake 20 dollar bill, what hope do we have that protesters won't be targeted in unfair ways? Or worse, that organizers won't be hunted down like animals and murdered like in Furguson? It would be unethical to not do everything in your power to protect those in this position.
secondly how do you plan to identify violent vs non-violent protesters from a static image? How would you find their identity afterwards? There is overwhelming evidence to suggest these methods are at best ineffective and at worst racist, and in either case will lead to innocent people being charged.

From my time in Portland, working at the courthouse as a court clerk during the Occupy movement, when hundreds of transient “protesters” camped out in the park, it is not surprising that some of those folks would OD or end up dead for reasons entirely not related to protesting but instead related to their unfortunate life circumstances. I do not know if the same is true of Ferguson, but the article does not seem to provide any evidence of calculated retaliation against protesters.
Is this more or less than the number of attendees we would expect to die based on Ferguson homicide rates and approximations of the number of attendees? I couldn't find that in the article.
Also, what's the theory that this isn't a coincidence? The police are murdering random protestors for some reason?
What percentage of young people will die in a given year?
What percentage of those will happen to be community organizers?
What percentage of those will die by being shot in the head in a car that was then set on fire to annihilate forensic evidence?
Doesn't take too many steps out to get into the realm of zero percent probability that this is random chance
