What is the point of filming the abusive behavior if you don't show the evidence to police and animal control?
WRITTEN complaints should also be filed with both Animal Control and the police. The latter can also be shown the video of the kids harassing your dogs when you respond to the cop who is investigating that filming.
Should AC and the PD each continue to fail in their functions, a letter to your mayor, town manager or board of selectmen may be in order. You may also wish to discuss harassment orders with an attorney. The WA and your county bar associations can assist with referrals.
The foregoing is for general information purposes and does not establish an attorney-client relationship.
