....and my answer is as follows:

remember those who can 'slow down time'? remember the 'sloths-on-the-system'?

...the blue-eyed and the brown-eyed.....go figure.

krasinski and blunt....not your 'average' hollywood couple....a couple of sloths-gone-to-the-bad....difficult to handle...one of the FBI had got a 'knife-in-the-back' and that knife wound had come from blunt - she had been responsible for 'that one' upon a trigger command from krasinski.....

sorry, not 'knife-in-the-back'.....more like 'sustained a knife wound'....

.....and then somehow 'everything got confused' after 'that one'....resulting in 'no conviction'.....no cctv....no conviction.....go figure - as to 'why' that was.....

slo-time...slo-mo....slomo-time....i can 'see' somebody, who had been within krasinski and blunt's immediate territory - with a radio desk - in one of the houses - across the way, from their residence.......he had then upped and gone....packed it all up and gone....
