I'm going to take a more diplomatic approach. I understand your frustration, but what is going to happen when the neighbors start missing dogs? They will say you've been complaining about them and now all of the sudden they are missing their dogs. You saidthat you had documentation of all the events,which means they will too.
Personally, I would load them in my vehicle and take them to the pound. Over a period of a few weeks all the dogs will be there and you will have removed them legally. If you just go blasting their dogs you're likely to face criminal prosecution.
Thegood thing about this plan is it will cost the owners money and time in order to get their dogs back.I find that money is a great motivator.
If they don't pick them up, problem solved too.
