Can't say this guy would be my first choice for a neighbor, but he I'd take him in a heartbeat over the busybody who called the county over a deck being built in a neighbors backyard. From the small bit I read, seems like ol' Mongo was minding his own business until some jerk decided to butt in where he wasn't wanted. Sometimes, when you invade a persons privacy, they get irritated.
In my years as the local code enforcement officer, I've seen stuff like this happen time and again, and the Mongos of the world will always win, because they have nothing better to do than retaliate using the system. Better if everyone minds their own business. If someone isn't actively endangering you and yours, who cares what they do on their property? It isn't as though the fellow was storing garbage or having wild orgies in his backyard. HE was building a deck. The neighbor(s?) stirred the pot, and this is what he(they?) gets.
Be kind to your neighbors, folks. You never know who just might be a devious and vengeful nutjob with lots of money.
