What's wrong with a father wanting details as to how and why his <unarmed> daughter could have been shot to death by uniformed, on-duty, police officer?
God forbid one of our daughters meet up with that level of 'badged' fool, but, if something nearly as sad and tragic ever did happen... what would any of us want for an investigation?
(The 'memorial' hurt someone's feelings, so the cops had it torn down.. whole 'nuther issue, entirely, I think.)
