Yep, I can't tell you how many times Greenfield got a heads up on Armed Robberies or Foot & Vehicle pursuits on the crazy border they have with Milwaukee. Oh yeah I can't leave out the officer assist Greenfield gives MPD which they never could of done if they wern't monitoring. Sounds like at least one Greenfield squad has a scanner or UHF radio.Umm...."tykes" like him might not be able to listen, but neither do the many surrounding law enforcement agencies (Greenfield, MCSO, North Shore agencies, etc). Many of those burbs use to listen in to Milwaukee to catch description of incidents that occur near their borders. The above quote kinda sounds like a anti-interoperability to me. Just my 2 cents.
Oh yeah, last summer Greenfield canine caught a armed robber on the Milwaukee side of 27th, after hearing MPD say robber ran that way. The guy was hiding in some bushes.
