On December 3, the Wikipedia article on the death of Eric Garner read in part: "Garner raised both his arms in the air and was then put in a chokehold from behind by officer Daniel Pantaleo." Later that day, it changed almost imperceptibly: Garner didn't just raise his arms, he flailed them, and Pantaleo's takedown may have been a headlock, not a chokehold. The subtly pro-cop edits didn't come from some impartial third party, but an IP address registered to the NYPD. They weren't the only ones.
