There's the rub; I too would like to have the snazziest bike they make. However, there isn't a department in the country that doesn't have to submit their budget through a raft of eagle-eyed bean counters.
"But chief, this bike costs 1595.99, whereas you could get this one for only 999.99!" I had to fight for years to get a bike for each officer in the program. "Can't you just raise or lower the seat?" Long, detailed memos about fit, comfort, health, and so forth resulted. We are now in a position where everyone who rides has a bike that's fitted to them properly.
I have extensive experience with bike repair, so I do all our department's maintenance. I do see many local departments hauling their bikes in to the LBS for minor repair-at shop rates. The local police academy offers both basic and advanced mechanic courses; wonder why they don't take advantage?
I'm considering this as my "retirement" job, actually....Traveling police bike repair guy!
