Not sure what you are referring to here. Could you clarify? The law enforcement training I received went into exquisite detail about the types of searches that were permitted under the Fourth Amendment and subsequent case law, an area which is continually evolving. The Fourth prohibits unreasonable searches and seizures, not all searches.

I learned more about the Constitution in LE than I ever did in school.

Unfortunately I am sure you can cite some instances of police misconduct, which does happen. But that doesn't appear to be what you are referring to...
