Beafer, you do spout some crap on here. If you're that interested in how the Police Air Support Unit operate, instead of asking the man in the village who is so far behind the latest CAP documents, why not give them a call and ask them. I'm sure they'll be more than happy to put your mind at ease and you'll get the answer from the horses mouth rather than the horses arse.
To answer one of your questions; yes there is someone at DTVA who monitors what goes on at night. They are more than competent in calling 999 and having the local authority RFFS attend any incident.
As above RFFS would have done naff all for the Glasgow incident.
