Taxpayers paid for all the military radios, too. But that doesn't mean the .mil is going to run in the clear when stateside. If OPSEC and COMSEC is a real concern for them (which it should be), then they should probably run a split model and have a publicly available channel for basic, non-impacting stuff. Don't a lot of Dept's already do that anyway for SWAT situations?

As for interagency/other depts. issues, they've known about the lack of integration of commo systems and processes as a real, true risk and threat to the lives of police, firefighters, and EMTs since before 9/11. 9/11 drove that home in a very painful way. They still haven't fixed it, so unfortunately the guys on the street will continue to get the short end.
