Sorry for being unclear: the roided up and jacked cops are one problem. The overweight ones are another. The former are more likely to have problematic attitudes (specifically: roid rage) than the latter, which your proposed physical fitness test would not catch. And I'm noting that you might be surprised about the level of aerobic fitness in some fat people (the latter).
