ziga:

I guessed you must have missed it.

But, It has been on the news daily that the boy's father informed the US embassy in Abuja about his son's radical behaviour and contacts weeks before the attempted bombing.

He was interviewed by the CIA, who did not disseminate the information, which is a big failure on the side of the states.

 The fact that the dad made an heroic move by informing relevant authorities on his concern about his son and for the fact that this your man wasn't radicalised in Nigeria goes to show that this isn't a Nigerian problem.
Yes, he has a nigerian background but the evidence so far shows that he had nothing to do with Nigeria for quite a while.
I won't be suprised if the US and other western intelligent agencies take advantage of this situation to use soft means to infiltrate Nigerian institutions.
Nigeria do not have proper institution or structure  to deal with issues like this but I hope Nigeria would do everything to condemn this heinous act with every resources they have. I am sure Nigerian do not have this kind of mind set!
