1. Criminal Justice Process: The Investigation
The criminal justice process includes everything that happens to a person from the moment of arrest, through prosecution and conviction, to release from jail or prison. There are separate state and federal criminal justice systems.

2. Arrest
An arrest takes place when a person suspected of a crime is taken into custody. The police may have an arrest warrant, which shows that a judge agrees there is probable cause for the arrest.
To show probable cause, there must be some facts that connect the person to the crime.

3. A police officer may use as much physical force as is reasonably necessary to make an arrest. However, a police officer who uses too much force or violates a citizen’s rights can be sued under the federal Civil Rights Act.

4. A police officer does not need probable cause to stop and question an individual on the street.
However, the officer must have reasonable suspicion to believe the individual is involved in criminal activity.
The reasonable suspicion standard does not require as much evidence as probable cause.
Therefore, it is easier for
police to stop and question
a person than it is to arrest
a person.

5. Search and Seizure
The Fourth Amendment entitles each individual to be free from unreasonable searches and seizures and sets forth conditions under which search warrants may be issued.
In evaluating Fourth Amendment cases, the courts seek to balance the government’s need to gather evidence against an individual’s right to expect privacy.

6. Traditionally, courts have found searches and seizures of private homes reasonable only when authorized by a valid search warrant. A search warrant is a court order issued by a judge who agrees that the police have probable cause to conduct a search of a particular person or place. However, there are many circumstances in which searches may be conducted without a warrant.

7. Even so, these searches must be reasonable under the Fourth Amendment
Even so, these searches must be reasonable under the Fourth Amendment. If a court finds that evidence was collected as the result of an unlawful search, the evidence cannot be used against the defendant at trial. In general, school officials are allowed to search students and their possessions without violating student’s Fourth Amendment rights.

8. Criminal Justice Process: Proceedings Before Trial
Every criminal case goes through several standard proceedings before it reaches court. In some cases, these proceedings eliminate the need for a trial.
Booking and Initial Appearance
Booking is the formal process of making a police record of the arrest.
The accused person first provides some basic information for identification purposes and then is fingerprinted and photographed.

9. Within a short time of arrest and booking, the accused must appear before a judge. The defendant has an attorney appointed or is given the chance to obtain one. At this stage, the judge decides if the defendant will be released on bail or remain in jail while awaiting trial.

10. Bail and Pretrial Release
Bail is an amount of money that an arrested person puts up in order to be released from jail while waiting for the trial.
If the person fails to return for trial, the court keeps the money.
Sometimes the court will
release a person before
trial without requiring bail
because there is very little
chance the person will
attempt to flee.

11. Information
A prosecutor’s information details the nature and the circumstances of the charges brought against a defendant.
This information is a formal
criminal charge filed with
the court based on the
information collected during
the initial investigation of the
case.

12. Preliminary Hearing
A preliminary hearing is a screening process used in felony cases to decide if there is enough evidence to make the defendant stand trial.
If enough evidence supports the prosecutor’s case, the defendant will proceed to trial.
If the judge finds no probable
cause, the case may be
dismissed but this does
not necessarily mean that the
case is over.

13. Grand Jury
A grand jury is used by many states in place of the prosecutor’s information or a preliminary hearing.
It is a group of 16 to 23 people who determine whether there is enough evidence to show that a person has committed a crime and should go to trial.
Only the prosecutor submits evidence to the grand jury. Neither the accused nor his or her attorney is allowed to appear.
A judge is not present and rules of evidence do not apply.

14. Felony Arraignment and Pleas
After an indictment or information is issued, the defendant must appear in court to enter a plea.
If the defendant pleads guilty, the judge will set a date for sentencing.
If the defendant pleads
not guilty, the judge will set
a date for trial and ask
whether the defendant
would like a trial by jury.

15. Pretrial Motions: The Exclusionary Rule
A motion is a formal request that the court make a ruling or take some other action.
Common motions include
a defendant’s motion to
obtain certain evidence
from the prosecution, a
request for more time to
prepare the case, a request
for the trial to be held in a
different location, or a motion
that certain evidence should
be excluded at the trial.
