Forget the matter of what emergency services might be allowed to do - you are a mere mortal just like the rest of us.
There are rules that we have to follow, lest we live in anarchy. Take a look at the rules that apply here - you can start with those in the CAA's CAP168, CAP670 and no doubt others. Look at the terms of all of the licences and approvals that are issued to go with the radio stations involved. Then take a look at the WT Act and the associated ITU Regulations.
The rules have been put there by people who see the big picture rather than one small and insignificant corner of one's own world. Sometimes those rules become outdated. If you think the rules are wrong then put your argument to rulemakers - but make it an argument instead of simply saying you don't like the rules or you don't see why the rules are the way they are.
