Yeah, even a HD would've kept up, but what are you gonna do when you catch him? Still haven't legalized shooting for evading arrest, even in your fine country (though it would lessen the risk to the public from high speed chases). I think keeping the perp in sight and following from a safe distance was the right call. It sure didn't provoke the idiot to drive even more recklessly and kill someone in the process. Hats off to a thinking officer.
