I quoted them. What I said was based on them, and upon what I understand the Supreme Court has said about them. I'm not a lawyer, so I could be wrong. Instead of just slamming me, why not explain where I got it wrong? Even if you think I'm beyond convincing, you'd be helping others to not make the same mistake I have.
But not, you just had to score points.
Fair enough.
Theoretically explained, the 4th Amendment is a balance between the individual's interest in liberty and society's interest in order. There are times when the individual has to win, and there are times when society has to win. The 4th Amendment is probably the single most important provision of the Constitution.
The 4th Amendment, by its own words, does nothing but protect you against "unreasonable" searches and seizures (seizure = detention/arrest). What that means is that, if it's reasonable (and that's a determination made under the circumstances), the gov't can do whatever it wants to you.
So, there are really two parts to a 4th Amendment question. First, is what the gov't did reasonable under the circumstances - if so, the analysis ends there. Second, if what the gov't did was unreasonable, did either reasonable suspicion (to justify a brief investigatory detention) or probable cause (to justify a full-blown search or arrest) exist?
Let's apply that to the airport security setting. Is it unreasonable for there to be security procedures which, as a general rule, aren't particularly intrusive and involve a minimum of time and inconvenience on our parts? While we can quibble about the details and effectiveness of what exists, I don't think too many people are going to tell you that the concept of airport security is unreasonable.
What about a detention/arrest for carrying cash (assuming nothing else)? Without more, I'd say that's unreasonable on its face. So, does the possession of a large amount of cash create R.S. or P.C.? In my mind, by itself, no - but what if it's coupled with something like a one-way ticket to San Diego, and the passenger ain't from San Diego? Again, in my mind, that's a little more suspicious, but still doesn't meet R.S. What if that's coupled with something like a rental car agreement for a return drive from San Diego? Still more suspicious, but it may or may not reach the threshold.
And that's how the analysis works.
But, the bottom line is that the 4th Amendment doesn't protect you against a search or seizure until it becomes "unreasonable."
