Failed prosecutions are no reason to roll back protections against unconstitutional search and seizure.
Our criminal procedural class in law school was getting tired of the Fourth Amendment 鈥 the one that protects 鈥減ersons, houses, papers, and effects against unreasonable searches and seizures鈥 and requires warrants based on probable cause before the police can look for evidence.
One of my classmates had had enough. She felt that all of this was silly. These rules, exceptions, and exceptions to exceptions were pointless. The police got the evidence. The guy is guilty. And now we can鈥檛 use it? He鈥檚 freed on a technicality. Is that really how we should look at this?
The exclusionary rule means that when the police or other law enforcement officers violate someone鈥檚 constitutional rights, then prosecutors cannot use that evidence gathered as a result of that violation against the person.
That鈥檚 the exclusionary rule. And it still manages to upset people.
Some feel that crime is so rampant and so egregious that we鈥檙e hindering police efforts to reduce it.
That鈥檚 what frustrated my classmate so much. The exclusionary rule can be devastating to the prosecution鈥檚 case. Strong, incriminating evidence just vanishes. Why have such a rule?
It wasn鈥檛 always this way. In the early decades of the 20th century, state police forces didn鈥檛 have to abide by the exclusionary rule, only federal agents in federal court.聽
Think about those old detective novels and movies. The cops burst into a smoky room where gangsters are counting money or doing something illegal, a detective punches someone in the face, and the case is closed.
There鈥檚 no search warrant. There鈥檚 no elaborate way to, as Sen. Kurt Fevella recently put it, 鈥渇igure out a way so we can break legs.鈥 What鈥檚 the big deal?
Consider the case that put the exclusionary rule on the map.
The defendant was a difficult, strong-willed woman 鈥 and that鈥檚 how her loved ones described her.
In 1957, the Mississippi native Dollree Mapp moved to Cleveland, Ohio, divorced from an abusive boxer husband and living with her daughter.
Then the police came over. Someone tried to blow up Don King鈥檚 house (yeah, the same guy made famous for promoting Mike Tyson in the 1980s and 鈥90s) and suspected Mapp was hiding the bomber in her home. They demanded entry to search the house. Mapp called her lawyer, who advised her not to let them in without a warrant. She did just that and the police left.
More officers returned hours later. A lieutenant waved a piece of paper at her and said it was a warrant. Mapp demanded to see it. The lieutenant refused.
Not taking no for an answer, she grabbed the paper from him and stuffed it into her blouse. Such a bold move from a woman of color must have surprised the police. One of them asked, 鈥渨hat do we do now?鈥
An officer stepped forward and announced he was 鈥済oing down after it,鈥 struggled with Mapp, and reached into her blouse to get the paper back. She never got to read it. No one did.
The police handcuffed Mapp, went into her house and sure enough found the suspect hiding in her house. But they didn鈥檛 leave. They searched every room and opened every box and drawer. They found books and nude sketches considered obscene. Although Mapp told them that they belonged to a long-gone lodger, she was arrested for possessing obscene material 鈥 a felony in 1957.
It took the jury 20 minutes to convict her. The judge sentenced her to up to seven years in prison.
The suspect, by the way, was cleared of bombing King鈥檚 house.
Mapp appealed her sentence and lost in the Ohio courts. It was far from surprising. As one professor later wrote, what the police did was 鈥渘othing extraordinary; it was an everyday fact of life for blacks and other racial minorities. Police throughout America were part of the machinery of keeping blacks 鈥榠n their place,鈥 ignoring constitutional guarantees against unreasonable arrests and searches and those that barred the use of 鈥榯hird-degree鈥 tactics when questioning suspects.鈥
But Mapp persisted and appealed to the U.S. Supreme Court. Her case made history. In 1961, the Supreme Court held for the first time that the states were obligated to enforce the exclusionary rule against local police. It would not be limited to federal courts anymore.
The Supreme Court explained that 鈥渢he right to be secure against rude invasions of privacy by state officers is . . . constitutional in origin鈥 and 鈥渨e can no longer permit that right to remain an empty promise.鈥 It is not 鈥渞evocable at the whim of any police officer who, in the name of law enforcement itself, chooses to suspend鈥 the Fourth Amendment.
Of course, that was Earl Warren’s Supreme Court, and the justices changed the way police investigate crime and the way we prosecute people. It was before the conservative backlash led by William Rehnquist and decades of Supreme Court justices who have watered down the exclusionary rule and made it a difficult doctrine to understand.
And while the erosion has been accelerating for generations in federal court, the exclusionary rule is strong in Hawaii. The Hawaii Supreme Court recognizes the need to deter police misconduct while investigating crime and even goes a step further.
The state Supreme Court has also made it clear that trial courts cannot allow tainted evidence to be used .
It means the courts should not give prosecutors a pass for using tainted evidence. If the guilty go free because our law enforcement violated the law, the exclusionary rule says so be it. As Justice Sonya Sotomayor 鈥渨hen courts admit illegally obtained evidence as well, they reward manifest neglect if not an open defiance of the prohibitions of the Constitution.鈥
So going back to my classmate鈥檚 complaint. Freed on a technicality? No way. The Fourth Amendment isn鈥檛 just a technicality. And is this how we should look at it? Absolutely.

I object!The exclusionary rule has always seemed like a mechanism to punish the police, prosecutors, and we, the public, when a police investigation or the acts of specific police officers, itself violates the law and civil rights of the suspect.Wouldn芒聙聶t charging both the police and the suspect if evidence is found of a crime having been committed be a fairer way to both discourage police misconduct and criminal acts? Seems like "inevitable discovery" , and other deprecations of the rule do serve justice better than this original doctrine. How does the tying the hands of the uninvolved prosecutors to make a case without "tainted" evidence result in a more just outcome? It seems like it is often a technicality that causes a search to be thrown out, at least if you watch a lot of Law & Order episodes that are "ripped from the headlines" .How does two "wrongs" end up making anything "right" to society?

My question is, what is the penalty for officers ignoring this Constitutional right? If there is no penalty, will not ignore it?

This is a nice story from your law school days about a case decades old. Glad these days we have a strong defense bar and competent judges that serve as "checks and balances" to any state action.
