There was an ex-MI5 security expert on BBC news 24 in the early hours of this morning.
He was more or less saying what Aloha and Springchicken and others have said. If you see a young Asian male with a rucksack or briefcase then you have to heighten your sense of awareness.
As he said, its not because we are being racist, but because in security speak, they meet the profile!!!!!!!!
Thats all there is to it really, the colour of their skin, religion, age is incidental. The fact is that the profile we have right now is what we have. We can't change that, only the bombers can!
I suspect that the Modus Operandi will gradually change and in time we will be looking for different risks - possibly female, possibly white, possibly 50+ who knows?
I work in London and commute 4 days a week, it would take me all day to get to work if I got off the bus everytime someone fitting the profile got on it and waited for another one to come. So I don't expect to be putting much of this into practice myself. However, I can understand how someone might not be prepared to take that minute risk right now.
On the other hand I am desperately sorry for the vast majority of people who meet the current profile who are just going about their business. What a miserable position to be put in! But the people who put them in this position are the suicide bombers.
Blu, WWW et al - i really am sad for you and your families right now
