Sorry Albs, but the chap was an illegal being chased by armed police. They told him to stop, he didn't... End of the day, he could have avoided the situation 
I agree fully.
Many years ago I was unfortunate enough to find myself staring down the barrel of more than one police marksman after they mistook me for our downstairs neighbour leaving home one morning (we lived in an upstairs maisonette at the time, and the front doors were right next to each other).
However in that particular case I was sensible enough to do what I was told, when I was told to do it.
The end result of that incident was that the only "injury" (if that's the right word) sustained was a few hours of me & my ringpiece recovering from the initial scare of staring down the barrel of several SA80's (or whatever they were at the time).
Yep, certainly applies in this case... Shortly after a massive terrorist strike in London a man with a backpack refuses to stop for Armed Police
Did the correct thing IMO. If they hadn't shot him and he had been another madman with a bomb they would have been slated for that too
I do believe that he was running to catch his train that was already on the platform (at least that was one excuse put forward).
However I believe that any normal person who was being shouted at would at least stop for a second to take a look behind them regardless of how much of a hurry they are in (especially the way the police shout orders).
Regardless of his immigration status, he didn't deserve to die but he brought that upon himself IMHO.
My only issue with police being armed is when you get nutters like that police officer at the G20 march who attacked that Tom guy from behind while he was walking (partially staggering) AWAY from the trouble's and obviously a threat to nobody.
There was absolutely no need for that at all, and the police made it worse for themselves afterwards by letting the officer get away with it.
At the end of the day, if you have someone presenting a serious threat to others then that individual has to be removed from the situation.
It's always nice when a situation ends peacefully, but unfortuantely it won't always go that way, especially if the perpetrator is cranked up on alcohol or drugs.
