Such a facility would inevitably be misused against people for a disturbing variety of
reasons. That's why it will never happen, and that's why such matters are best left in
the hands of trained, skilled and well-regulated investigators. We have all seen the
effects of surveillance societies and hopefully some of us have learned something
from those disastrous mistakes.

A point-and-click informant system seems like a nice idea on the surface when
you sell it with an anti-crime or anti-terrorist gloss but the end effect is the same
with very real and sometimes irreparable consequences to the accused and to the
community. That's why we have courts and the justice system.
