I guess this is the part where I tell you that 90% of what you hear about the killdozer guy is complete hogwash. and a lot of the "documentaries" are about as fantasy as Harry Potter.
the man decided to live in what before was the office area of the garage he bought, was surprised when an industrial building was put up in an industrial zone (why do you think the garage was built there in the first place?) got upset that the city didn't connect him to the sewer lines for free (it would have required installing and operating a sewage pump alongside the actual sewer lines) and was told to install a septic tank like many Americans. He was then fined for dumping his literal shit into the local water supply.
he was a petty, spiteful, greedy, deranged, vindictive and straight up evil person
