True to their word, the activists of Anonymous' #OPFerguson have released two hours of raw audio from police and EMS dispatch calls on August 9, the day 18-year-old unarmed Michael Brown was shot and killed by a police officer in Ferguson, Missouri.

In the interest of public transparency, we're posting the audio here before we've had a chance to go through all of it. Please consider helping us transcribe it or flagging significant events on the audio timeline for fellow readers in the comments below. We'll be updating and adding background along the way.

Note: This is not an exhaustive record of calls from that day. This particular file covers St. Louis County's dispatch; additional city of Ferguson police calls, which may offer more extensive information, have yet to be released.
