I certainly don't deny the sheer uncompromising idiocy of the people who actually did this. Nor do I have anything against Barbara - she's a lovely lady. But the fine itself just had me in stitches. A fine for walking into a building with the alarms sounding? What exactly is it going to be paying for, in a worst-case scenario? My funeral? It's my business if I want to win a Darwin Award. The building's on fire, I don't think my presence within it is going to damage it further.
I'm not saying people should walk into burning buildings - just that fining them is absurd. Apart from being unjustifiable, it's ineffectual: are headphone-wearing potheads* going to, henceforth, think "Whoa, there, an entrance! There's that fine in place now, I better check whether the alarms are going off..."? If on the other hand they're deliberately going into a burning building, if they're that deranged, is a monetary fine really going to stop them? I suspect not.
*I don't mean to imply headphone users are all potheads. It's just a stereotype I find amusing.
