This from Steve Redick:

Once again, thanks to Kevin Kirkley for hooking us up with this. Four recordings from the riots.¬†I’m told the last two parts are rare and seldom heard.
My father was an officer on the west side when these fires occurred, and my mom recalls having to drive him to Engine 7’s house when they issued the recall for off-duty members. I was only a kid, but I remember hearing all this on the radio, and being very scared when they left, fearing my dad would get shot or hit by a bottle or rock. Needless to say he had quite an experience, but came home in one piece.
