Sundays are very much "off" days for many BBC local radio stations. Ours was barely populated after 2pm today, with one or two people recording shows, and the occasional passing broadcaster (including one gentleman who appeared to have come in purely to ring up National Rail Enquiries and yell at the poor lady whose job it is to man their phones on a Sunday night).

But we'd better hope Al Qaeda take a similar approach to their weekends, for two reasons. Firstly the massive barriers which traditionally guard the entrance to the car park have been down for the last day or so, presumably because they've gone for a burton again. This means that, despite having the sort of security developed to keep the Russians from infilitrating local radio and gleaning precious travel bulletin information, any terrorist only has to nip round the front and they can walk in without bothering to scale any of the more formidable defences.

Secondly, we have many, many cameras all around the complex to allow our security guards to keep watch over things like the barriers, be they down, up or otherwise (once they caught a car containing a local band coming in to record a live session - it tried to follow a friend in without letting the barrier go up, and the barrier elevated the car at a hilarious angle, wrecking it in the process. Amusingly the band were called The Skies.)

So, in theory, even if the terrorists had been rota'd in for Sundays and noticed the absentee barrier, they'd have been picked off by our crack security squad in seconds. Especially if they did more than 15mph down the drive.

But it would seem the security staff, watchful as ravenous hawks when the barriers do work, take the malfunction of the barriers as their cue to chillax a little. I got in this evening to discover the pair on reception giggling at a computer screen. On further inspection they were watching clips from The Wedding Singer on YouTube.

"It's alright," I said, "I'll let you know if there's any terrorists in the building."

(In reality I don't begrudge them their YouTube at all. There's about as much likelihood of us being the centre of a terrorist attack, on a Sunday or otherwise, as there is of me winning the Reading Half-Marathon. Or even running it.)
