There is a diary currently on the rec list that claims that police beat and arrested teachers at an ALEC protest in Chicago today. The comment thread is full of outrage, naturally.
However, there is a significant problem - neither the article nor the video linked to in the diary supports the claim. The article describes the protest, the video shows three people dressed in black, one shirtless, being arrested.
Nothing in the diary, nor in the comments, supports the diarist's claim that the police "...are doing snatch and grab arrests and beating teachers."
