What W1HAF can appreciate, but many who have never been in public safety and/or just read all the trade mags and similar stuff - things that are so dynamic do not fit actual real world conditions.
People can arm chair stuff like this all day long, but until they are actually put into situation, you will find out that the best laid plans (usually put together by people with little to no field experience) go out the window rather rapidly.
Many of the trade articles are written by industry representatives and people who live in cubicles in DC who do not have field experience by are tasked to write SOP's, guidelines and other such mandatory directives tied to $$$ but have really no concept that some of that stuff doesn't work.
My current beef are from radio shops that have employee's who have no experience but can tell police chiefs how things should be done. (my current situation - we came up with new templates with real talkgroup names but the radio shop thought their way was better - and guess who gets to foot the bill for reprogramming to how it was suppose to be done!)
The last thing we want to have happen is to have a police officer needing to look down at a radio while navigating busy roads and then do the same running after someone. One channel works great.
I will not comment on this system or what may or may not be in place on a console level (and I don't think anyone here can intelligently comment unless they have in-person knowledge of the console options and layouts) to arm chair what happened, and was there. We may never know, but its not our place in a scanner enthusiast forum to critic public safety operations when you only know one side of the radio.
