The former head of Pakistan's nuclear research programme, who is also an outspoken supporter of Islamic radicals, has been arrested in Pakistan and placed in "protective custody", the government said today.
He was detained with another scientist from the Pakistan Atomic Energy Commission

Sounds like they need them for insurance purposes. It depends on what the definition of the word "arrest" is.
It sounds more like "we're keeping them handy, just in case."

It sounds more like "we're keeping them handy, just in case."

Or they were moonlighting. I hope not but it would make sense seeing that bin Laden wants 100k troops on the ground. Using a nuclear weapon on a hundred troops at a time is a waste even for him.
