Speculation .No one knows the motive at this point other than the shooter(s)....... And you are playing into the hands of willfully submitting your soul and character to political ideologies. Branding yourself as "proud conservative or proud liberal " exposes your own weakness to stand on your own particularly when you default to an automatic hatred of others who don`t share your beliefs. Who killed Melissa Hortman , Her husband and their dog? 'Stupid Liberals" ? Play this game and your just as well like any of them that pulled the trigger. "conservative or liberal" . These murderers allowed themselves to play the conservative/liberal tribal game to hate. Sickening waste of life including their own.
