My 2-yr-old is in a front-facing convertible, and my 11-mo-old is in a rear-facing convertible. My toddler is in the middle.
Rear-facing is the safest way to ride. The middle of the back seat is the safest place. If you have more than one child, though, the least protected should go in the middle, so the forward-facing instead of rear-facing, or booster instead of harnessed, etc.
I don't know why the officer would tell you the middle is not safer, unless he really had no idea what he was talking about (they don't require carseat training in police academy, after all). Everything I've ever read or heard on the subject says that middle is indeed, the safest place.
