I agree with you PunchingJudy, the whole point is that ambulances are being called for the wrong reasons, and that callers are able to either manipulate the situation so that a Cat A is demanded or the despatcher is unable to take the risk not to send an ambulance. It only needs to go wrong once to be headline news. Tom et al are doing this job to help people, certainly not for the money (!) and yet in the press they will be vilified for a judgement call that goes wrong. So frustrating.
