That is typical of just about any media event anymore. The media seems to have changed from just reporting the news, (decades ago) to trying to put a slant on the news.
I love how the cop just leisurely strolls along the line of protesters, with the stream of OC from the can looking as if it could be Round-Up being sprayed on weeds along a fence. Replace the cop's uniform with a polo shirt and jeans, remove the protesters, and replace the can of mace with a nozzle of a plant poison sprayer, and his pose would be exactly the same. Just my two cents worth.
