[A] day after 4 suicide bombers got away after failing to carry out their mission, a man dressed in summer in the typical garb of a wannabe-shaheed - bulky clothing ideal for covering up a vest packed with nails and explosives - emerged from an apartment complex which had been under the eye of plainclothes policemen. Upon emerging, he then began to make his way towards the tube, further arousing police suspicions. After entering the tube station, he was approached by up to 20 plainclothes officers who presumably identified themselves to him; rather than stopping to answer their questions or even just screaming "Help" or "What do you want?" to attract the attention of tube staff, he decided to run down the escalator, knowing armed policemen were pursuing him, and ignoring all commands to halt, he leaps over a turnstile right into a Tube carriage, acting for all the world as if he were a terrorist whose cover has been blown, and who is desperate to accomplish his mission regardless. Having done everything within his power to arouse the suspicions of policemen who are aware that there are still any number of suicide bombers out on the loose, he is promptly shot 5 times in the head, exactly in compliance with official police policy for dealing with suicide bombers who could otherwise set off their explosive charges even after being apprehended.
But then, sandor_baci's observation also rings true.
"A bomb belt with wires coming out" -- and the "Asian-looking" man, running from plainclothes policemen, is shot dead on the tube platform.
1) If you're Asian-looking and persons not identified as policemen express an interest in altering the course of your day, don't run. If they are racialist thugs and you stand still they may kill you, yes. But if they are plainclothes policemen and you run, they WILL kill you.
2) Leave your iPod at home.
