"It really is peculiar why of all possible letters, they chose this one. Someone was asleep at DP."
===========
No one at DP was asleep. The DP has always been fearful of an "armed public".....meaning CCW permits for Law-abiding Citizens who are not murderers, robbers, or rapists....but who would like to be armed to protect themselves from murderers, robbers, and rapists. 
-
So The DP picked perhaps the one and only letter that supports the "opinion of The DP" "the best".....which isn't saying much.
-
If The DP had done the public a favor and reported exactly what time the first 9-1-1 call was received, what time the dispatcher notified the patrol cars (there's a time delay there of a precious minute or more), what time the cops arrived "on scene" (it takes a couple minutes there) and what time "entry was made" (after enough cops arrived to make it safe?)....the public would realize that shooting victims often bleed to death and the suspect is long gone before the first cop arrives.
