"Lake Stevens Police Commander Dennis Taylor said the man was apparently armed with a "high-capacity" rifle. Taylor added that "many"shots were fired and said that the police vehicles were hit "many times."

Is your MBR calibre capable of barrier penetration? May want to re-think that 5.56 option. High capacity IMHO is a drum or belt fed. When you throw flash bangs in a baby crib without accountability it's bound to cause some blow back. Police have brought this on themselves with minor infractions ending with dead pets or worse dead citizens. Nobody wants to interact with the police.
