Retweeted by Graham Cluley@PC_Winter Why announce publicly the threat level has changed if we don't have to act any differently? I don't get it.According to MI5, we just have to be "vigilant" regardless of the threat level.

Retweeted by Graham Cluley@jack_daniel nice one! The only colour coded terror level that should ever be used is "brown alert"@jaimeblascob Tom's an American. It figures.In non-security news, the games so far in the US Chess Champs have been amazing. #SinquefieldCup14 http://t.co/K7v3AoyEpV Go MVL!Remind me how am I supposed to act when the UK Terror threat level is raised.
