Years ago I remember some discussion about cell phones and there was
mention of a "black box" that supposedly was available to law
enforcement that could read the cell "book keeping" signals and
determine whether your phone was in the cell and (I think) read data
going to or from that phone.

We've had a number of robberies, a bomb at the Eurawan hotel shrine
and more to the point the machine gunning of a politician's car, it
must have been 4 years ago. In every case the police released CCTV
film of the event. Apparently even Bangkok has them "all over the
place".
But even more interesting is that many businesses, particularly gold
shops, have CCTV systems installed and there was a case a couple of
years ago about a foreigner who claimed to be persecuted by the
police, falsely accused of stealing from a duty free shop at the
airport.... After the CCTV film was shown on TV the claims of
persecution sort of evaporated :-)
Probably a sign of progress :-)
