The New York Times > New York Region > Videos Challenge Accounts of Convention Unrest: "For Mr. Kyne and 400 others arrested [at the RNC], video recordings provided evidence that they had not committed a crime or that the charges against them could not be proved, according to defense lawyers and prosecutors.

Among them was Alexander Dunlop, who said he was arrested while going to pick up sushi.

Last week, he discovered that there were two versions of the same police tape: the one that was to be used as evidence in his trial had been edited at two spots, removing images that showed Mr. Dunlop behaving peacefully. When a volunteer film archivist found a more complete version of the tape and gave it to Mr. Dunlop's lawyer, prosecutors immediately dropped the charges and said that a technician had cut the material by mistake."
