What makes you say that?
Well there was history before the land was bought the previous owners had had run ins with the Neighbors , dumping stuff and other property line violations and he let Ian known this. However as the previous owner was vacating the land he must have seen the two neighbours and said something along the lines of "This new owner wont take any of your crap so you better watch out". Ian I belive also said something inflammatory to them on their first encounter eventually there were further disputes that then that lead up to the attempted firebombing (and i was wrong it was his house they were attempting to set alight) and the shots and eventually Ian being acquitted of charges. The point is that the entire thing could have been avoided if instead of continuing the old neighbors dispute going Ian had went to speak to them maby had a beer with the guys the entire thing could have been avoided. Ian was and from what i understand of people who know him a confrontational hot head and that did not help his situation.
