This week’s Supreme Court decision in Kentucky v. King has civil-libertarians and marijuana policy reformers in an uproar, and rightly so, but it’s not exactly the death of the 4th Amendment. Here’s a look at how this case could impact police practices and constitutional rights.

It all started when police chased a drug suspect into a building and lost him. They smelled marijuana smoke coming from an apartment and decided to check it out, so they announced themselves and knocked loudly on the door. They heard movement inside, which the officers feared could indicate destruction of evidence, so they kicked in the door and entered the apartment. Hollis King was arrested for drugs and challenged the police entry as a violation of his 4th Amendment right against unreasonable searches.

In an 8-1 decision written by Justice Alito, the Court determined that an emergency search was justified to prevent destruction of evidence, even though police created the risk of such destruction by yelling "Police!" and banging on the door. The determining factor, in the Court’s view, was that police had not violated the 4th Amendment simply by knocking on the door. Since the subsequent need to prevent destruction of evidence was the result of legal conduct by the officers, the events that followed do not constitute a violation of the suspect’s constitutional rights.

Naturally, any fan of the 4th Amendment can look at this scenario and wonder what’s to stop police from "smelling" marijuana and "hearing" evidence being destroyed any time they have an urge to enter a particular dwelling. What does destruction of evidence sound like anyway, and what doesn’t it sound like? Doesn’t someone jumping up to destroy evidence sound the same as someone jumping up to answer the door before police kick it down? It’s hard to argue with anyone who sees this result as a blueprint for facilitating not only widespread police actions that circumvent the warrant requirement, but also more innocent people being killed in their own homes in misunderstandings that could have been prevented by just a little patience from police.

These are very valid concerns, but it’s also true that in the immediate aftermath of any unfortunate Supreme Court ruling, there’s a tendency to commence eulogizing the 4th Amendment and proclaiming that our freedom from unreasonable searches and seizures has been abolished once and for all. That’s not the case here any more than it was with any number of previous rulings we wish had been decided differently. It’s not a fatal diagnosis; it merely sucks.

The fact that police were chasing a suspect when they entered the building and the fact that they smelled marijuana coming from the defendant’s apartment and the fact that they heard suspicious noises after knocking were all factors in the legal outcome. Remove any one of these conditions and the case might have been decided differently. In other words, this Supreme Court decision does not mean police can start knocking on doors randomly and bursting in any time they hear a sound coming from inside. They must already have probable cause to believe there’s a crime taking place and, fortunately, any prudent citizen can take measures to prevent their home from reeking of probable cause.

Ultimately, the lesson here is something we’ve been emphasizing at Flex Your Rights for a long time now: stay calm, don’t expose yourself to police attention, and know your rights in case something happens. Police often knock on doors without a warrant, so your best move is just to stay calm and make an informed decision about how to handle the situation.

If you prefer not to answer, which is your legal right, then do so by waiting silently for the officers to leave. If you choose to speak with them, stepping outside is a smart way to keep them from claiming to detect criminal evidence within your home. Unless they have a warrant, they may not search or even enter the home without your permission. Don’t give it to them. Finally, understand that if the officers do have a warrant, your legal options are limited to the point that you should just focus on not getting hurt. In the event of any kind of negative outcome, remain silent and discuss your options with an attorney.

It’s a shame that we even have to prepare people for situations like this in what’s supposed to be a free society, but modern drug enforcement practices are so prone to error and abuse that every citizen should know how to protect their constitutional rights in an emergency situation. As the Supreme Court continues to reduce the scope of our 4th Amendment protections, understanding how to properly exercise our remaining rights becomes more important than ever before.

We’ll continue to do our very best to make this information easily and widely available.
