I'm not saying they planted anything. I'm not saying they didn't either..... it could very well be a form of post incident damage control that an unscrupulous officer might use to justify his actions or to defend these stops. "See, see.....we find dope doing these." Doesn't matter though because my (and anyone else's) suspicions or lack thereof mean squat in this case. The point is that is is an un Constitutional search and seizure, period, imo. The fact that the supreme court has deemed to allow them doesn't change that....again, imo.....
These and dui checkpoints are both the kinds of things that the founders feared and from which they wished to protect the people.
And for the record, the law is that an officer must have "reasonable suspicion", defined as
"a standard established by the Supreme Court in a 1968 case in which it ruled that police officers should be allowed stop and briefly detain a person if, based upon the officer’s training and experience, there is reason to believe that the individual is engaging in criminal activity." before further probing which attempts to establish "probable cause"
"In Terry v. Ohio, we held that the police can stop and briefly detain a person for investigative purposes if the officer has a reasonable suspicion supported by articulable facts that
criminal activity is afoot, even if the officer lacks probable cause."
"Probable cause" means reasonably reliable information to suspect there is a "fair probability" that a person has committed a crime, or that a search will reveal contraband or evidence. "Reasonable suspicion" is a strong suspicion, even if based on less information of a less-reliable nature, that a person is involved in criminal activity or may be armed and dangerous.

NONE of the above standards are met in checkpoint stops. It seems clear to me that the Supreme Court is at odds with itself.
