the only one that can fix the problem are the people that make money from the calls, the phone companies.
as long as the phone companies make money from this it will continue.
and saying the phone company does not know the true origin of the call is a lie.
this is a very bad idea that will do nothing to make anyone safer, it just further erodes our right to privacy and gives the police more power that they do not need.
"Religion is something left over from the infancy of our intelligence, it will
fade away as we adopt reason and science as our guidelines."
