I fail to see the relevance of this. Once one "neighbor" physically assaults the other, then the "disagreement" becomes "assault".
A property dispute is of course no justification for an assault which would be better characterized as attempted murder.
I think that the only defense for this lunatic is metal illness, but the defendant’s lawyer has stupidly based the justification for the “assault” on a “long running dispute” which implies a valid reason.
Paul will own this guy.
