There was a conference for (i think) the International Bicycle Police (or something like that) in Charleston WV a few years ago - the shop I used at the time was one fo the shipping destinations for the conference, and they must have had 200 bikes shipped in from all over the world for that conference! They seem to try to use sturdy bikes, and lean towards MTBs - Charleston WV has some bike patrols, and I think they're cute. They also travel with about 40 pounds of stuff attached to them. They do have races against each other at these annual conferences while wearing full gear - all that heavy cop stuff (gun, flashlight, radio, handcuffs, etc...
So, next time you're out on the trail with a 25 pound bike, think 35 pounds plus another 10-15 pounds of gear on your body, tooling along city streets all day long - rain, shine, wind & snow, and give those bike cops the cudos they deserve!
As with mud, life, too, slides by.
