This is a good plan; we’re not talking about a law-enforcement issue here. We’re talking Hostis Humani Generis. And this crap tends to run in families.
If Little Mo’ blows himself and bunch of innocents up, his entire family, Big Mo’, his his mothers, brothers, sisters, their spouses, and their kids, should be rounded up for wood-chipping.
But allow them to buy their way out with information on Little Mo’s recruiters, handlers, trainers, bomb-builders, paymasters, etc. Any valid info gets the lot off...
And, when you catch them, you know what to do with them, and THEIR families...
And keep going up the chain.
It is the first modern recorded case where the terrorists were forced to hunt and capture or kill their own and turn them over to the non Muslim authorities the hunters answered to.
