Sadly it's another set of examples of being seen to "do something". And, of course, a minor 'success' for terrorists by imposing further inconvenience and costs.
So now any intended terrorist will simply detonate [or whatever] at ETA -1 hour. He probably has a watch, so he doesn't actually need the moving map anyway. That's a giant step forward for airline security.
The 'seats upright' is, I guess, to make it easier for the cabin crew to notice unusual activity during the last hour. Which is fine if the intent is to drop the aircraft onto a city. If not, it makes no difference to security at all.
As several of you have said, the answer lies in more aggressive profiling before boarding ... and, of course, making effective use of the information already available on certain passengers.
PS - I'm a white British Anglo-Saxon Protestant, I'm over 60 and have little need for 72 virgins. Can I move to the front of the queue please?
