Chattanooga police officers harass and detain two men running cellphones and taking images of the Riverwalk and a nearby chemical plant. The men equipped with a police scanner test the limits of their liberty of movement. Officers demand “ID” and “try to get to the bottom of everything” and “determine you guys are not suspicious.” An officer admits they are not required to show ID. “You’re not detained,” the officer says, but they are detained and not free to leave. The officer says a factory security guard who had called police has, by virtue of that phone call, given cops authority to detain the two men. “Being suspicious or having security call in is not a crime,” replies the unnamed activist. Disturbing. 39 minutes.
