What better than to gin up TERROR! in a war weary US/UK population than planting a laptop with naughty bio-fetish dreams.
1) Nobody looked at the laptop for months. Really? Honest? Didn't even bother to check that for intel from your competion/enemy in Syria? Oh, Mr Journalist? Here maybe you like this, we are just using it for door stop.
2) Put laptop in hands of semi-credible news magazine looking for a big scoop to boost image.
3) Sit back and watch Fox News make it the number one story for the next 60 days while government(s) figure out how many troops are going to go where.
4) Announce troop deployment because of TERROR!
Now.. perhaps it is all legit. But to ignore the plant angle is to be led down the WMB path again with blindfold on. And nobody does this kind of stuff better than the UK, a country with a long and sordid history of using "journalists" to plant fake "information" to justify government actions and policies.
