problem is that in Germany the full data-take is shared 50% spooks - 50% cops, routinely. Whilst in UK the cops hardly get a look at the full-take material as it is too secret, (no one knows about it), and so it can't be used in court to avoid challenges as to where it might have come from, and god-forbid that the defence team should ever have a trawl through the raw muck! That wouldn't be cricket
