Probable Cause In Criminal Investigation

1.Probable cause is a set of facts surrounding a specific circumstances that leads a “reasonable person” to believe an individual is committing, has committed or is about to commit a crime. Probable cause is required in the instances of an arrest, search and seizure and the issuance of a warrant. To ESTABILISH reasonable cause the officer can use any trustworthy information. For example the office could use his/her experience, informant information, first hand observations or knowledge, victim reports, anonymous tips, or hearsay.

2. Investigation—sufficient evidence, known as probable cause, must be gathered to identify and support a legal arrest of a suspect.

Fourth, the facts that are alleged to establish probable cause must “supported by Oath or affirmation” (Hall, 2016.) In a

It is true that reasonable suspicion is not probable cause to elicit some sort of a reaction for something or for someone but

Probable cause is defined as a reasonable belief that a crime has been committed, that evidence is at the place being sear5ched or on the person being searched, or that a specific person is believed to have committed, is committing, or will commit a certain crime. Law enforcement cannot just go to a judge and say they have probable cause for a warrant. To obtain a warrant law enforcement needs something to substantiate their belief. The standard for probable cause to be met is for any reasonable person to believe based on the evidence or observations presented that indeed either a suspect has or is engaging in criminal activity, or that evidence exists at a certain location. Not all searches require probable cause to be established. The exception to the probable cause is reasonable suspicion. An example of this is a customs search. A custom search requires no warrant or probable cause be presented. But if a custom agent is going to detain a traveler for an extended

This comprises of indirect evidence which aids in detection of crime while not fully proving it. The probable cause sources are enough in some cases while for others further information or evidence needs to be provided. If the judge wants to issue search warrants, then the probable cause must highlight that the person got involved in criminal activity and the crime has taken place.

While reasonable suspicion does not require hard evidence, it does require more than a hunch. A combination of particular facts, even if each is individually insignificant, can form the basis of reasonable suspicion. For example, police may have reasonable suspicion to detain someone who fits a description of a criminal suspect, a suspect who drops a suspicious object after seeing police, or a suspect in a high crime area who runs after seeing police.

A probable cause is established at the time of a preliminary hearing or preliminary examination. The hearing judge decides whether there is a combination of facts and circumstances that would encourage a reasonably intelligent person to believe that he or she should commit a crime. A probable cause must be examined from different angles in order to closely understand the mind of a person with non-criminal background. Those with a non-criminal background are exposed to committing crimes regardless of how clean their criminal record might look. Usually, the jury’s determination of a probable cause impacts the final decision of the case and how serious the law breaker’s punishment will be.

It is vital for law enforcement to determine whether a search warrant, arrest warrant, or both is needed. When an arrest is to take place within a dwelling where reasonable privacy is expected, law enforcement must determine whether or not the prospective arrestee lives there. If the person to be arrested lives there, only an arrest warrant is needed. If the dwelling belongs to a third party, an arrest warrant and a search warrant is necessary. In order to comply with the Fourth Amendment’s protection of privacy, police must secure the appropriate warrant(s) and knock and announce their presence.

The two-pronged test was developed to “determine whether that information demonstrated probable cause” (Ingram p.172) where the first part of the test, “an informant’s veracity and reliability had to be determined prior to finding that the informant’s information supplied probable cause” (Ingram p.173) In this part of the test the police had to prove that the informant was a believable person” (Ingram p.173), such as having a history of “giving a reliable and truthful information to the police in the past, and might even implicated himself or herself in a crime just to prove to the police that he or she is telling the truth. The reliability of certain personalities as an informant such as the “local priest, mayor and another police officer

Reasonable suspicion is a reasonable likelihood that a crime has been, is being, or will be committed. It is a reasonable belief based on facts or circumstances and is informed by a police officer’s training and experience. Reasonable suspicion is seen as more than a guess or hunch but is less than probable cause. Probable cause is the logical belief, supported by facts and circumstances, which a crime has been, is being, or will be committed. The difference between the two are the fact that probable cause has evidence or is fact based whereas reasonable suspicion is a hunch.

Meeting the standard of probable cause requires a demonstration to the judge or magistrate that a crime has occurred, or is occurring and that evidence relative to that crime will be found at a particular location. The investigator must swear, under oath, that the information establishing a probable cause is true to the best of is or her knowledge But in certain cases getting a warrant might take time so based on reasonable suspicion police can go ahead and still conduct the search. The police can conduct searches using numerous ways such as first-hand information if someone tells them you have something your not suppose to based on that information they can go ahead and conduct a search.

Thus, this leaves this determination up to the courts to decide case by case. Probable cause quantitates specific levels of suspicion and is based on facts and prudent belief of guilt, thus allowing a law enforcement officer to perform a warrantless search. Probable cause is more substantial than reasonable suspicion pertaining to the justification for an investigative detention. (Devallis Rutledge, 2010).

Reasonable suspicion is evaluated using the "reasonable person" or "reasonable officer" standard, in which another officer in the same circumstances could reasonably suspect a person has been, is, or is about to be engaged in criminal activity. This would mean that a crime occurred and the said suspect is more likely than not the perpetrator. The suspect has the mental capacity, the obvious opportunity, and the capability to perform the crime under investigation.

Probable cause is a requirement which can be found in the Fourteenth Amendment that must usually be met before an arrest can be made, before being allowed to conduct a search, seize property, and to receive a warrant which is related to the alleged crime. Probable cause is considered a level of reasonable belief, probable cause must be based on facts and not an assumption. In civil court, a person can be sued if they have probable cause, and in criminal court, the defendant can be prosecuted or arrested if they also have probable cause. If the officer cannot prove probable cause, unfortunately, the evidence then becomes inadmissible, and the evidence will be thrown out.
