Barry, your posting got me to wondering about some other aspect of microwave
hazard which has been an infrequent subject of conversation with some of my
friends who drive cars with funny lights on top.

You posting to me indicated you were knowledgeable in this field so I would
like to know what you feel the risk is to police officers with X-band radar
units mounted on the inside or outside of a rear side window pointed forward.

I have always felt that the operator was in risk with this placement, but have
not seen any reports either pro or con.

Comments...?
