Common sense and law aren't your strong suits I guess.
Court decision set legal precedents. Legal precedents make changes in criminal guidelines; in courts and in law enforcement. Changes in law enforcement guidelines opens or closes doors to law enforcement procedures. In this case it opened doors. New criminal procedures and guidelines may be applied across the spectrum of possible criminal cases making the legal precedent applicable to cases that in no way resemble the case by which the precedent was set.
Little fascists like you think it's just fine to twist or ignore the meaning and intent of the Constitution when it suits your agenda but somehow you indulge in the fantasy that those excesses won't be used in other ways. Ways that can be used to gore your ox when political winds shift as they invariably do.
Go back to class, you don't even know algebra much less basic logic.
Or, just the opposite. Some goofy doped out druggie's lawyer tries to argue a silly approach to the constitution and the court slaps him down. The criminal procedure stays the same and is in fact validated, the doper goes to jail, the cops keep his pot and another school yard is saved from a drug pusher. Try again F. Lee
Where in the constitution does it guarantee the right to keep and bear a bale of dope?
