This is really a dangerous precedent that the KPD is setting. On the one hand, I think that JM would have been better off shooting the guy in his apartment. But on the other hand, if you consider the demographics of the people involved, had he shot the intruder, there might have been the same or worse outcome.
There is no way in a just world that an intruder gets the benefit of doubt before the homeowner. There simply is no justice in America. Keep in mind that Knoxville is in red state territory. Imagine if this would have happened in the suburbs of DC, Chicago or Portland. JM would probably already be on the gallows.
