Folks
This is called one human reporting on another human to the powers that be. Perhaps if the people in that city were aware which cab companies were participating in the snitch for a pat on the back program the cost may put a stop to it.
I can find no reports on any terrorist being prevented from any actions except for lawful americans being rousted.
If I report my neighbor for being a terrorist I can be sued by my neighbor if they can prove to a "Rational man or woman" that I should have known better.
Hmmmmmm!
