Sorry, but, wouldn't there need to be some form of motivation and reason other then location to suspect me of murder. How about all those others that are stuck in the same traffic jam, are they not suspect as well. No, that kind of thinking, although something to be aware of, is not really feasible and even though it isn't perfect our legal system is a little more sophisticated then that. Perhaps in a dictatorship it would be common, but, we haven't reached that yet. As for keeping that information, well, there must be some pretty bored agents collecting stuff on me. I doubt I would ever be on the top of the list of probable suspects, so, no I don't worry excessively about it. I've served on enough jury's in my life to know that it isn't all that simple to convict someone of anything. Can it happen, sure! But, when figured in the totally per capita numbers it is a very small number.
