Nothing was staged. Nothing was "off."
This is what they do.
It is your lack of experience in the world of violence that makes your mind unable to grasp the inhumanity in these humanzees.
Your reaction is disbelief. Just like the poor girl here, not grasping the severity of her injuries and violence of this subhuman attack. Disbelief. Shock. Inaction.
This is just one of the many times everyday this happens. If not for the video you would not have heard about it. As it was, took several days before someone leaked it to the press. The video is arousing the people's fear and anger. Yes it is everywhere.
Unfortunately one of these homunculus live not a hundred meters from me. He has a criminal record worse than this. He walks after each arrest, worse than his last. He knows me from the prison system. I know him as well.
He is dangerous to anyone living yet he walks free.
Have yourself some fun and practice using a search engine. Find out who is in your neighborhood has killed, maimed, and burned people and yet walk free. Maybe even your next door neighbor.
