Target, or its attorneys, appear to be insane
A mental case run into a Target, pursued by some bystanders (reasons for pursuit unstated). Mental case begins stabbing a teenage girl. One of the pursuers, Michael Turner, makes a flying tackle and drags the mental case off her. Now Target is suing Turner.
According to story, the mental case had stabbed a friend of Turner outside the store, and Turner and others pursued him inside.
My guess from the above stories: the teenager has sued Target, and target made a third-party claim against Turner and the other pursuers, claiming that were partially to blame because their initial pursuit of the mental case led to the stabbing. Good luck with the jury -- if it gets that far.
