Mr. Harris, I do want to propose some thoughts to you. I have not scoured your City's ordinance, but at first glance find your City's site to be use unfriendly and very difficult to find anything one might need to learn there.
Your character has been assassinated. You have been branded as a dog killer, not just by Mr. Gapp and his 85 flyers, but by the news article by an ignorant reporter who twisted the entire story to make you look evil. If I had only read the newspaper article and did not know the truth, I would think you were off your rocker and just wanted to kill the dog because he showed up on your property.
He has ruined your reputation and defamed you, and this cloud will always be over your head, and that of your family.
This is how everyone in your neighborhood will see you now.
We know this is not the truth, and so do you.
$6,000-12,000 is a huge chunk of money. However, and this is a BIG HOWEVER, if you get an attorney who will work on contingency, this amount of money is only what you would spend for your DEFENSE. When, not if, you win your case, you can collect everything that Gapp owns.
Your homework is to find out what he is worth and make that your goal with a good attorney. To reap $1,000,000 and give Mr. Gapp a new name of GONE, will be very well worth it. You have made a good start. Don't stop now.
It might be a good idea to sue the newspaper too!
