Market not working well
"...concerns that the market might not be working well."
I confess I don't understand much about economics, but it seems to me that if you have a single monopoly supplier for an essential emergency service, that's not a market at all, and it's hardly surprising that the customer is in a poor bargaining position.
Surely Airwave should just have been a set of open protocols, plus a compatibility testing regime. Then multiple suppliers of the actual equipment could have been appointed, giving some opportunity for a competitive market to operate. Or am I being naïve?
