I read on freerepublic.com the speculation that the shooter might have been using a motorbike. That makes sense if he has to run from the police: a motorbike can go between cars and I guess many can go faster than cop cars. Plus, they can fit in the backs of vans and box trucks. However, I tend to notice motorbikes more than cars, and some of them, but I guess not all, make more noise than many cars. Would a rice burner or similar attract notice in the areas where the shootings have occurred, or are there a lot of them on the roads?

Also courtesy of FR, here's an actual useful idea: have the cops shoot flares in the air to light up the inevitable wooded area. Of course, it would also make any targets easier to see, but I don't think it would matter.
