I often work with police on campus, and during one day while they were bothering me for video footage of someone using a found campus card then buying $12 of soda in a vending machine, I asked what I could do about my $600+ stolen bike. He said that stolen bikes were one of their lowest priorities. (While $12 of stolen soda warranted a full investigation.)
Within one week, I found my bike locked up at a bike rack, with a tune up! Waited for the guy to come out, and made the same cop come out to write up the report in order to return my bike to me.
Law enforcement priorities never really make much sense to me, but anywho...
