Probable Cause

想象在深夜回家的路上,看到一个苏spicious person wearing dark clothes, looking into a car window with a flashlight, and carrying a crowbar. There have been multiple reports of vehicle break-ins in the area. Would you A) assume they are just locked out of their car or B) assume they were about to break into the car to steal? Now imagine the same scenario in the shoes of a police officer. The fact the person looks suspicious, carries a blunt object, and is in an area where break-ins are common would be probable cause for an officer to detain them.

This article focuses on the use of probable cause. Along with the definition of probable cause, we will look at how law enforcement uses probable cause during arrests, affidavits, and hearings. We will look at a case example involving probable cause and differentiate probable cause from reasonable suspicion.

Definition of Probable Cause

Probable cause is the legal grounds on which a law enforcement officer can conduct a search, seize property, or arrest. Probable cause is the reasonable belief by a law enforcement officer that an individual is committing a crime, has committed a crime, or will commit a crime and is based solely on facts.

There are four types of evidence that can establish probable cause:

TheSupreme Courthas stated that the concept depends on the context and is very imprecise. The court has often opted for a more flexible stance on probable cause in cases with more serious charges.

Fourth Amendment Protections

The Fourth Amendment of the US Constitution protects individuals from searches and seizures by government officials deemedunreasonable under the law.

Home:The searches and seizures at an individual's home are considered unreasonable without a warrant. However, there are times a warrantless search is lawful:

• the officer gets consent to search the home;
• a lawful arrest of the individual has been made in the immediate area;
• the officer has probable cause to search the area; or
• the items in question are in plain view.

Person:An officer may briefly stop a suspicious individual and ask them questions to relieve their suspicions if the officer observes conduct that makes them reasonably believe that a crime will occur or has occurred.

Schools:A warrant isn't needed before searching a student under a school's care and authority. The search must be reasonable under all circumstances of law.

Cars:An officer has probable cause to stop a vehicle if:

• they believe that a car has evidence of criminal activity. They are authorized to search any area of the car evidence can be found.
• they have reasonable suspicion that a traffic violation or crime has occurred. An officer can pat down the occupants of a car during a lawful traffic stop and have a narcotics detection dog walk around the exterior of the car without reasonable suspicion.
• law enforcement has a special concern, they are authorized to make highway stops without reasonable suspicion (i.e. routine searches at border stops, sobriety checkpoints to combat drunk driving, and stops to ask motorists about a recent crime that happened on that highway).

Probable Cause Affidavit

所写的证词可能原因是加勒比海盗ting officer and given to a judge to review. The affidavit summarizes the evidence and the circumstances leading to the arrest; it also contains witness accounts or information from police informants. A probable cause affidavit is written when an officer makes an arrest without a signed warrant from a judge. Cases of warrantless arrests usually occur when officers see someone breaking the law and arrest them at the scene.

In determining whether there was probable cause for a search, seizure, or arrest, the court must find that under the same circumstances, a mentally competent individual would think a crime was being committed. This procedure is done to make sure police aren't arresting people without reason.

Arrest on Probable Cause

When an officer announces that they are placing an individual under arrest and restrains them, they must have probable cause to believe that person committed a crime. Generally, the amount of evidence needed to establish probable cause is more than a suspicion that a crime was committed but less information than needed to prove guilt beyond a reasonable doubt.

Probable Cause Hearing

A probable cause hearing is a preliminary hearing that takes place after charges have been filed against an individual. The court hears witness and officer testimony to determine the likelihood the defendant committed the crime. If the court finds there is probable cause, the case moves forward to trial.

A probable cause hearing can also refer to a court proceeding that determines whether an officer had a valid reason to arrest an individual. This hearing determines whether law enforcement can continue to hold a defendant who hasn't posted bail or hasn't been released on their own recognizance. This type of hearing occurs in conjunction with the individual's arraignment or first appearance before the judge.

Probable Cause vs. Reasonable Suspicion

Reasonable suspicion is used in the various contexts ofcriminal lawinvolving search and seizure. It's a legal standard that requires a law enforcement officer have an objective, articulable reason for suspecting an individual is involved in criminal activity. Essentially, it's the step before probable cause. Officers can only briefly detain an individual based on reasonable suspicion. Reasonable suspicion can be thought of as a justifiable hunch whereas probable cause is an evidence-based belief of criminal activity.

Probable cause requires stronger evidence than reasonable suspicion. At the point of probable cause, it is obvious a crime has been committed. Additionally, aside from an officer, any reasonable person looking at the circumstances would suspect the individual of being involved in criminal activity.
