You and I vehemently agree.

But even if the police where you live were perfect, handing them the keys to the internet wouldn't resolve crimes committed outside their jurisdiction.

I see why the idea is appealing to politicians, but even they ought to think twice about the risks inherent in third parties accessing their most private communications - given that whatever sides of the political aisles they sit upon they are likely to be much more interesting targets to better resourced assailants than us average schmucks.
