But teenage antics can also go too far, and when they do, police have to step in. Large numbers of rowdy youth had been gathering at the Inner Harbor for the past couple of weekends as the weather got warmer, prompting increased police patrols, Mr. Harrison said. Initially around 30 officers were deployed, and by the end of the night about 60 were brought to the area because the crowds were so large. Police body camera and Citiwatch video footage from Saturday provided by the police department showed kids darting in and out of traffic almost getting hit by cars. Groups also ran across the promenade, along Pratt and Light streets and other parts of the Inner Harbor, randomly breaking out in fights, the 5 ½ minutes of video, self-selected by the police, showed.
