The Fourth Amendment has limitations. Just as the Second Amendment, the First Amendment, and ALL Amendments.
The most common example is that anyone entitled to the benefits of the U.S. Constitution may not shout "FIRE!" in a crowded theater if there is not, in fact, a fire.
There is, for example, NO 'right' in the Second Amendment to OC. Nor is there for CC for that matter. Nor is there any 'right' to OC provided in the Indiana Constitution under Article 1 Section 32.: "The people shall have a right to bear arms, for the defense of themselves and the State."
Does the right to OC exist in Indiana? Yes. But it is implicit, not specific. Just as it is with the 2A.
So ANY notion that 'it MUST apply to everyone ALL the time' is nonsensical, and baseless. There ARE, and historically have been, times when even those rights outlined in the Constitution have been limited. And no doubt, will be again at some point in the future.
It's not JUST a matter of, as on poster opined, "have you even read it?". It's a matter of IF one understands the Constitution, and the limitations that even that document has.
I'm not sure where anyone would get the notion, but there appears to be an opinion that, in the case of the Boston manhunt, the LEO's "Can't search without a warrant because the Fourth Amendment says so! I have the RIGHT!"
That's NOT what the 4A says. 4A is a right against unreasonable searches (and seizures), which may not be performed without warrant and affidavit.
Searching for a madman that has already detonated multiple bombs (even after the marathon) killed at least 4 people, wounded another 180 or so, and which HE (NOT the Police nor the MA National Guard) had the Boston / Watertown areas under siege would, likely, NOT be considered "unreasonable" even IF it imposes upon those citizens.
Lest you forget, it was because of the scumbag Tsarnaeva brothers, NOT the LEO's OR National Guard that folks were 'forced' off the streets, away from their jobs, parks, and daily lives, and 'restricted' indoors.
Would some prefer the alternative of letting such a maniac run loose, perhaps? Perhaps attend the Indianapolis area marathons with the same agenda?
'You' (whomever) may very well NOT be 'scared of that scumbag'. Understood. But he sure as hell isn't 'scared' of you, either. And he PROVED it by killing and wounding children, women, men, and LEO's. Dzhokhar Tsarnaeva was in TWO violent gun battles in less than 24 hours, and that p.o.s. is still here despite being shot multiple times. I think that qualifies him as having sufficient battleground credentials to be considered 'hardened'.
Probably better to subject the town to a temporary limitation of their 4A protection for the benefit of him NOT murdering more innocent lives, eh?
Wow, it boggles the mind that our unenlightened father's generation of cops could even solve a crime.
I mean, this is not the first "mass" anything. There have been shooting and bombings.
And yet, they were able to do it without trampling.
How did those poor people do it?
