Where to start?
How about having hundreds, or potentially, thousands of radios on a single voice path.
Or having different functions, thay don't necessarily have to talk to each other, on the same voice path.
A single, solitary voice path, for an event of that scale is in itself asking for problems. Never mind access contention. With that many radios.
Ok my creds, if it matters: DHS/FEMA ICS100, ICS200, ICS700, ICS800
I guess I am a basement dweller (but no basements here in CFL) that someone here is referring to because I had the audacity to state, quite accurately that the Butler fiasco could have been avoided using VHF FM simplex.
There were not hundreds or thousands of radios. There were a couple dozen USSS and County PD SWAT operating on dissimilar systems and using text messaging to convey early, critical information about the shooter, that was missed, ignored, not conveyed for some 19 minutes. Had the first County PD unit that spotted the shooter sneaking around with a range finder, picked up a radio, any radio, any technology that was common with USSS by some means, a shared radio, a ICS tent, etc,. The message would have been conveyed instantly (OK slight delay in P25) and the shooter would have been intercepted or shot dead before he could have sighted his target. You don't need or want dozens of talk groups for the surveillance of the arena. If someone is working logistical stuff, positioning motorcade etc,. not carrying a long rifle, maybe they can be on channel 2.
I have been in this game since 1976, 17-plus years with the /\/\ being taught that their way is the only way (Amen), and the remainder asking customers what they NEED (often that is different than what they think they want, were promised by vendors) and translating to an SOW/RFP. I will confess to being a Luddite of sorts, because there is pain to be endured by being an early adopter of technology, and likewise a pain being a late adopter as accelerated planned obsolescence is what keeps the vendors playing golf.
I have also gotten a fairly good idea how decisions are made at the upper levels. Throwing money at a problem is easy (Its taxpayer money dummy), and how better to spend money and reward vendors (the elite) than by "buying the latest state of the art". I am sure discussions are going on right now on how to integrate cellular text messaging into P25 voice or some such fancy Rube Goldberg.
The problem was lack of an operational Incident Command and/or sharing of radios. Had that first responder been heard on radio by USSS, the outcome would have been better. But no, it will be a technological band aid.
