What do you think looking at the photo?

Behind the most powerful protest photo of the year in Ukraine

Wait a minute.
What do you think by looking at the photo?

I feel the photo creates a negative image of the officer but I am somehow not able to find a reason for it.
How I feel may not be correct all the time.

Context : 

A disheveled Ukrainian man and his son walk in the streets of Kiev, a protest site for the past four months. Both their faces are drenched in blood. They’ve come across a Ukrainian soldier or police officer dressed in riot gear. Reuters freelancer Vlad Sodel snapped the photo as the man and his son exchange glances.

My conclusion:
Without full context, the information can be misleading. So better to have no view until complete context is known. Believe me, this comes handy in more cases than you think 
It would be especially useful in avoiding media speculation. Good day! :)
