I've noticed that, too. I think for them a bicycle is just a practicality that they can use in congested inner-city areas to get around faster. We've had cops on bikes for a few years around here, but it doesn't appear to have changed the situation for cyclists one bit.

One of the disappointments in life I've had to learn to accept is that bike cops (here in Philadelphia, anyway) are not bicyclists, have no interest in cycling, and do not see their role as having anything to do with cycling. Bikes, to them, are just a faster way to "walk" their beats.
