Thanks jwilson. You may be an out of state poster, but at least you have a genuine interest on what goes on here. If you take a look at productionguy's post history, you will see that he mainly just flutters around making smart alec replies to posts that do not contribute to the conversation.
Back on the Denver Public Schools system, I remember hearing a Denver Public School security officer supervisor on the DPS security channel talking about how he had to explain to a school principal what a button was used for after seeing it installed at his school without any warning. He was clearly not happy about what it was going to be used for. I did not realize why a "button" would be such a big deal to him until this story broke recently about the botched evacuation and the system that did not work.
And really nothing against the DPD officers that were on scene trying to get the kids out. They did their best. It is the new system that did not work. But I still have to say that the DPD PIO or whoever is sending out those tweets should have been called out in that story. The people that were interviewed (including staff, students, and parents) in the KDVR piece did say the evac did not go well at all. Even as an observer just listening I could tell the same thing.
