The Washington Post recently had an article about a State drug chemist (responsible for various drug tests) was not only a user of the drugs but had been falsifying drug test results which were instrumental in many peoples convictions and incarceration.
The article asks the question about whether the cases for which she provided evidence should be thrown out.
This shouldn’t even be a question.
For well over one hundred years, the Fourth Amendment existed without the Exclusionary Rule, the rule which makes evidence taken during an unreasonable search and seizure inadmissible at trial. Basically, the amendment depended on the good faith of the government not to violate it for its enforcement. In much the same way–and with much of the same success–that Blanche DuBois depended on the kindness of strangers. Then, in 1914, the Supreme Court of the United States realized that not everyone scrupulously adhered to the Fourth Amendment. Abuses actually occurred. So did sunsets, but not as often.
The Supreme Court ruled that a right without a means to enforce it is no right at all. To remedy this, it enacted by judicial fiat the Exclusionary Rule, as a means of enforcing the Fourth Amendment.
The Exclusionary Rule says the government cannot be allowed to profit, when it breaks the rules with an unreasonable search, so any evidence seized can not be admitted. To use a somewhat simplistic analogy (I like simplistic analogies. If more law school professors used simplistic analogies, I might have passed a few more courses.), the Exclusionary Rule is like calling back a touchdown pass for a holding penalty. The scoring team would not have achieved its goal, but for the fact that it broke the rules. So, rather than allow it to prosper from cheating, the team is penalized by having the play nullified. The Exclusionary Rule was established to enforce compliance with the Fourth Amendment.
In 1961 the Supreme Court ruled that the Exclusionary Rule was applicable on the states through the Fourteenth Amendment of the Constitution. Now, when state or local police conduct unreasonable searches and seizures, the evidence is not admissible at trial.
