This will obviously develop during the day, but there are a few things that need clearing up about this alleged “plot to blow up planes”: 1) was there specific intelligence that today was the day?, 2) would stopping people from having hand luggage make any difference to the threat? (i.e. can they blow up the plane from the hold?), 3) are we just freaking out because the “critical” Mi5 threat level has been made public* (i.e. how many other times have we been here before, but didn’t know?) Anyway, Allah bless the UK.
* The US-style threat level has only recently been a thing for public knowledge. The BBC keeps saying (and with great glee) that the threat level means an attack is “imminent.” Talk about whipping people up into a frenzy.
