Hi! Its been awhile
Maybe the police won't help because its not their jurisdiction and public shaming might get you in trouble.
How about contacting your local animal rights groups? Maybe they have the ressources to deal with these kinds of people. A quick google search brought up these names (but I'm sure you can find more):
