So something did get through the glass at least somewhat intact. Have the ceiling tiles (or whatever the material) been checked for entry and exit holes? Sounds like BPD is being less than diligent in seeking either a bullet or whatever object penetrated both the glass and the blinds.
Yeah, I'm bit perturbed the bullet wasn't found. Watch this...I'll find the bullet the next time I'm down at the office. I know Al personally, along with everybody else that was in the office at the time. If he says he saw ceiling tile debris coming down, it's so. I know where to look, based on his description in this story.
