This is a seemy mess, but I found this information. Thanks for your comments, I see we agree more than disagree...See what you think...
Yes, we agree more than disagree. I do think that the resource officer missed opportunities to perform much better —even alone and with a handgun—but the six minutes of total response time was a time compression that really necessitated significant training that I am pretty certain the officer didn’t have.
I bet that the department is sitting on dispatch tapes that prove that the resource officer provided them an identity. If correct, they missed an opportunity to make educated guesses that they were up against a lone shooter (the guys history reeked of being a loner freak) who was a teen and beatable if engaged quickly.
I am certain that the department didn’t train for success, or have policies that would deliver success.
The dispatch tapes, training records, training descriptions, and policies are all available by document discovery.
Finally, if these events AREN’T Monday-morning-quarterbacked after-the-fact, then improvements can never be made. They must be Monday-morning-quarterbacked. The truth must be discovered so that policies, procedures and training can be improved.
