SEATTLE -- The Seattle Police Department wants the public to share their photos and video of the May Day protests.
SPD on Tuesday said it wants to use high-tech analysis to create a detailed visual record of the May Day march and the people who participated in several acts of vandalism downtown.
Police specifically are asking for photos or video taken in the crowds before, during, and after "Black Bloc" members changed into and out of the matching black clothes they wore during the march.
Hundreds of people carrying wooden dowels and wearing similar black "hoodies," pants, and masks took to the streets on May 1, with some participating in acts of vandalism at retail stores and the old federal courthouse.
Seattle Police Sgt. Gary Nelson, who led the investigation into the 2001 Mardi Gras riots in Seattle's Pioneer Square, said SPD will use technology similar to what was used in the 2001 case to identify suspects in the May Day march.
Nelson said, "We need video and pictures from many different angles. It will take a lot of man hours to put the pieces together."
SPD said images and video can be sent to firstname.lastname@example.org.
