Can Police Follow a Suspect for No Reason?

Yes, police can follow a suspect for a reasonable period of time even if they have no reason to believe the suspect committed a crime.

Police do not need reasonable suspicion to follow a suspect in California if the encounter remains consensual. Under California law, consensual encounters between law enforcement and individuals do not trigger Fourth Amendment scrutiny. A consensual encounter occurs when a reasonable person would feel free to disregard the police and go about their business. For example, officers may approach someone in a public place and converse with them without any suspicion of criminal activity. However, the encounter becomes a detention if the individual is not free to leave or terminate the interaction.1

If the police action escalates to a detention, reasonable suspicion is required. A detention occurs when an officer restrains an individual’s liberty through physical force or a show of authority, and a reasonable person would not feel free to leave. Reasonable suspicion must be based on specific, articulable facts that suggest the person is involved in criminal activity.2

How Long can Police Follow a Suspect?

Continued police surveillance violates the 4th Amendment if it is unreasonable. Surveillance is unreasonable if it infringes upon an individual’s reasonable expectation of privacy or is conducted in a manner that is excessive or unjustified under the circumstances.3 There is no bright line on when continued surveillance becomes unreasonable. However, to violate the 4th amendment, the surveillance must be more than following a suspect for a short time. Ultimately the reasonableness of the surveillance depends on the specific facts of the case.

Additionally, California statutes clarify that law enforcement personnel may follow or surveil individuals. Officers can follow suspects as a part of their duty to investigate suspected illegal activity or misconduct. Their surveillance must be supported by articulable suspicion.4 This aligns with the principle that reasonable suspicion is necessary for more intrusive actions, such as detentions or searches, but not for mere observation or following in public spaces.

Can Local Police Stop Cars on the Freeway?

Yes. Local police can stop cars on the freeway or highway. In fact, any member of California law enforcement can generally enforce the laws anywhere in the state. This includes sheriffs, park rangers, harbor patrol, railroad police, and many other branches of law enforcement.

Why Can Police Stop Cars on the Freeway?

In California, almost all state and local law enforcement agencies have authority throughout the entire state. This means they can stop a vehicle on the freeway and can arrest persons for whom they have probable cause. For an exhaustive list, see Penal Code § 830-832.18.

Some of the better known state agencies are:1

  • California Highway Patrol
  • University of California Police
  • Cal State University Police
  • Department of Corrections and Rehabilitation
  • Department of Fish and Game
  • Department of Parks and Recreation
  • Department of Forestry and Fire Protection
  • Department of Alcoholic Beverage Control
  • California Exposition and State Fair Marshalls
  • Department of Cannabis Control

There are, however, many many more state agencies that have police authority throughout the state:

  • Department of Consumer Affairs2
  • Department of Motor Vehicles3
  • California Horse Racing Board4
  • Department of Housing and Community Development5
  • Department of Financial Protection and Innovation6
  • Department of Justice7

There are also many local agencies that have police powers anywhere in the state of California:

  • All county sheriffs and city police officers8
  • Community College Police9
  • Housing Authority Patrol Officers10
  • Municipal Security Officers11

Local agencies have some limits on their policing. Fore example, local police can only police:

  • Public offenses in their jurisdiction;
  • With permission from other law enforcement;
  • To prevent danger to person or property or escape of the perpetrator.

Three agencies from other states have limited police power to stop cars a freeway. They are the Oregon State Police, the Nevada Department of Motor Vehicles and Public Safety, and the Arizona Department of Public Safety. These agencies have police powers up to 50 miles inside California if:

  • The California Highway Patrol requests their help, or
  • Law enforcement services are necessary to preserve life 12

I Just Got Arrested, Now What?

After you are arrested, continue to assert your 4th Amendment right to refuse search (except when arrested for DUI) and 5th Amendment right to remain silent.

arrested

right to remain silent

It is very important to remain silent because your own statements can be used to convict you. Wait until your attorney is present before you make any statements to police.

Statements that seem innocent such as, “I didn’t mean to do it,” “I drank much earlier today,” or “he pushed me first,” are actually confessions to a crime.


Tips and Tricks to Remaining Silent

arrested

Confessions are an easy way for police to secure an arrest and for prosecutors to obtain a conviction. Although you have the right to remain silent, the police have developed strategies to get you to talk.

“if you didn’t do anything wrong, tell me what happened.”

You may be guilty of a crime even though you didn’t do anything “wrong.” For this reason, it is best to say nothing to police until your attorney is present.

waiting for you to start talking

If you start a conversation with police, you have waived the right to remain silent. Remember: “Any statements you make can be used against you in a court of law.”

“you have the right to remain silent…”

The Rule

If police do not give you this well-known Miranda warning, your confession could be excluded from criminal proceedings.

Miranda Limitation

However, the Miranda rule only excludes confessions that occur during “custodial interrogations.” Those are interrogations that occur in police custody, typically in a holding area or at a jail.

Police Strategy

Police usually follow the Miranda warning with “Do you want to waive these rights and talk to me?” You can invoke your right to remain silent by stating, “No. I don’t want to talk to you.” If you remain silent, police may continue to talk to you. You can re-invoke your right at any time by saying “I don’t want to say anything else, I want to talk to a lawyer.”


right to refuse search

It is also important to refuse search because evidence found during the search can be used to convict you. If you consent to search of your property, you waive your right to contest the search in court.

Exception: Arrested for DUI

If you are arrested for DUI, you must provide a blood, breath, or urine sample to determine you blood alcohol concentration (BAC). Failure to provide a sample can result in additional criminal charges AND further DMV action against your license.


Tips and Tricks to Refuse Search

arrested

Consensual search is any easy way for police to secure an arrest and for prosecutors to obtain a conviction. Although you have the right to refuse search, the police have developed strategies to convince you to consent.

“sign a consent to search form to get your phone back”

If police believe there is evidence of a crime on your phone, they will not return it to you unless you consent to search. We all “need” our smart phones, but you will likely be better off refusing search and picking up a temporary phone.

“if you don’t consent, we will get warrant”

You have the right to insist police obtain a warrant, except when you are arrested for DUI. Requesting a warrant will delay the police, so be polite and let them know you respect them and their job.

“if you have nothing to hide, let us search”

Your personal items are private and you have the constitutional right to refuse search.

“if you work with me, I’ll work with you”

Even if you cooperate with police, they are not legally required to help your case.

What Can I Say to Police?

  1. I respect law enforcement and the job you do.
  2. However, I am not going to consent to a search of myself, my property, or my vehicle.
  3. I will not resist you, but I will not consent to my detention, search, or seizure.
  4. Nor will I answer any questions without my lawyer present.
  5. With that being said, am I free to leave?

What Can I Do if Police Violated My Rights?

If you can prove police misconduct, the judge could dismiss your criminal case. You could also sue the law enforcement for violating your established constitutional rights.
