He’s finally arrested.
Minneapolis police are now facing heavy criticism for not arresting Sawchak before the shooting even though he had multiple complaints.
Members of the Minneapolis City Council, including Mayor Jacob Frey, pointed blame at the Minneapolis police department for not acting on any of the prior complaints against Sawchak and failing to arrest him immediately after the shooting. https://newsone.com/5658819/white-man-shoots-black-neighbor-minneapolis/
MN is not a stand your ground state. If you are threatened in public then you have a duty to retreat if able. However, MN is a castle doctrine state so if someone threatens you on your property then you are perfectly clear to use any reasonable means up to and including lethal force to defend yourself and your property. So your initial idea only works in MN if the threat took place on his own property of if he is unable to get away from the threat.
