The plain English wording says that you are safe from unreasonable searches. Everything hinges on the interpretation of "reasonable," which is not a matter of "plain English" because plain English doesn't define "reasonable" with sufficient precision.
In what world is using a damn airplane to get the location of mass numbers of people by exploiting their cell phones considered reasonable? It's ridiculous that people aren't in jail over this kind of bullshit.
only for lawyers... its obvious the concept is to protect citizens from govt dragnets... to anyone who isnt attempting to pervert the spirit of the law
You've gone from "plain English" to "spirit of the law" which is way different.
Again, I agree with you, but this position is not something you arrive at by just reading the 4th Amendment and then understanding its words without legal context.
