It's not really a policy change though is it? Aren't they enforcing laws that cyclists previously were breaking with impunity? I would like them to show their work too, but I don't really see the policy conspiracy angle to this.
Resources allocated in one realm means a dip in another. Using bad stats to justify a reallocation should be alarming to local residents.
If you've ever commuted via bike, you probably understand how little sense it makes to stop at every sign and roll no lights.
(Note that I'm not saying that these law breaking activities are equivalent; only that there are a multitude of laws that are not enforced, and a change in enforcement is indeed a policy change.)
