Re: "poor widdle snowflakes..." Et tu, Bomba Bob?
The main argument against your plan (aside from the coppers') is the issue of abuse. I mean abuse of this system by unscrupulous types. Maybe it could be made safe and maybe it couldn't, but it's new and with the current climate of technofear about digital security, It's going to be a very tough sell. The police won't really have to do much opposing because so many others will be doing it.
At least that's how I visualize it happening, could be wrong.
