I should hope that by now we all understand the absolute necessity of video and audio to show, to provide clarity and to counter deniability, the far left as it truly is.
Everytime I read about a protest by a Freeper or someone on the right and they don't do some basic photo/video/audio I want to pull my hair out! It isn't hard and it is so necessary. Without documentary proof it just becomes a we said/they said dispute.
I'm sure in this case there has been some pics/vids/audio done but, please, if you're gonna protest or counter-protest, document it! All you need to do is put on any lefty-leaning shirt and you can walk into the beast at will. A Che shirt will get you face time with leftist leaders at a protest.
