This little "debate" is gettng heated, but you should rethink this statement. Are you saying that if we don't happen to be cops, then we should not comment on their actions?
The Constitution was written for the people. It was written so the average uneducated American of an agricultural society in the 1700's could understand and function as an individual most of the time, and as a united people during times of duress. This is obviously a time of duress.
I have a deep and abiding love of the Constitution. I'm sick of it being twisted to mean whatever anyone wants it to mean. It means exactly what it says. Article IV protects us against unreasonable search and seizure. There is NOTHING unreasonable about asking to search a vehicle of whatever color on a street that has been used as an escape route immediately following another bloody and senseless crime.
This is not Iraq, this will never be Iraq. If the government just decided to throw up a roadblock to check vehicles for miscellaneous guns it would be a different matter, but obviously, that is not the case here. I find it ridiculous that anyone would even try to equate the two. If we don't start pulling together as a country we're never going to defeat the threats we are facing. Bashing the police for trying to protect us under these circumstances are not only counterproductive, they are downright dangerous.
