MediaMole may be able to tell us more - sounds like he/she is getting more off the tv than we are from the radio station.
I've been watching TV and listening to a scanner with Brookfield and New Berlin cops channels. Nothing interesting on the scanner, just getting roads closed and keeping out the media stuff.
TV report from witness...
"... someone came in at the beginning of the service... multiple shots were fired. There didn't appear to be any specific target. Congregation consists of 50-80 people... very peaceful people."
