I look at it this way: In Calvert there is a relatively new tactic where the speed trap consists of innocuous looking vehicles on the shoulder with one or more cruisers mixed in. I've not been caught by them, but have noticed them on the opposite shoulder gunning me in the oncoming lane. Very clever indeed. But this morning at 5 something when I was on my way to work and looking for possible police vehicles behind, in front, on the side, etc., I realized that their tactics have forced me to be more alert of my surroundings. Situational awareness saves lives. Even though it bothers me that they're doing speed limit enforcement instead of a few other things like watching intersections, I have to admit they're doing something that really does have a positive effect on my personal safety.
Kudos to Smokey the Bear.
