Actually, I had read all of that.  Those were, in part, rhetorical questions.  

The sworn testimony of the 'experts' in court will be interesting on those questions which actually do have real answers.  

Ballistics is not an exact science, but the other questions I raised will likely be answered for the jury's consideration by the experts hired by the Babb family  and the experts hired by the City's insurance company,  

If I point a weapon at you or someone you work with, how will you know whether it is loaded or not?  

Are you required to wait until I actually shoot you or one of your co-workers to determine if the weapon is loaded? (Legally, you are not.)

That will be an issue for a jury to consider, as well.
