Arrest Search Seizure.
This chapter covers what a Texas peace officer must know about arrest Search Seizure, along with the statute limits that shape each element, at the level of detail the TCOLE tests.
Chapter 10 study guide.
Almost everything in this chapter comes down to one question: how much do you know, and what does that amount of knowledge let you do? A hunch lets you watch. Reasonable suspicion lets you detain. Probable cause lets you arrest or search. Proof beyond a reasonable doubt is what the State needs to convict.
Learn that ladder first. Then learn the Texas articles that put it into practice: Chapter 14 (arrest without a warrant), Chapter 15 (arrest under a warrant), Chapter 17 (bail) and Chapter 18 (search warrants) of the Code of Criminal Procedure.

The levels of proof
The law recognizes several levels of certainty, and each one unlocks a different power. From lowest to highest: mere suspicion, reasonable suspicion, probable cause, and proof beyond a reasonable doubt.
Probable cause has two versions because an arrest and a search ask different questions. Probable cause to arrest asks whether a crime was committed and whether this person committed it. Probable cause to search asks whether seizable property will be found in a particular place or on a particular person.
Probable cause is judged objectively. An officer honestly believing they had it is not enough. The facts must be ones that would lead a person of reasonable caution to the same belief.
- Mere suspicion
- A hunch or intuition. Useful on the street, but it proves nothing in court and gives no power to detain.
- Reasonable suspicion
- Based on the totality of the circumstances, and a lower burden than probable cause. It supports a temporary detention.
- Probable cause to arrest
- Facts and circumstances within the officer’s knowledge, from reasonably trustworthy information, sufficient to warrant a person of reasonable caution in believing a crime is being or has been committed.
- Probable cause to search
- The same kind of facts, sufficient to warrant a person of reasonable caution in believing that seizable property will be found in a particular place or on a particular person.
- Reasonable belief
- A belief that would be held by an ordinary and prudent person in the same circumstances as the actor.
- Proof beyond a reasonable doubt
- The standard for conviction. Every person is presumed innocent, and each element of the offense must be proved to this standard.
- Brinegar v. United States, 338 U.S. 160 (1949)Defines probable cause to arrest.
- Carroll v. United States, 267 U.S. 132 (1925)Defines probable cause to search.
- Beck v. Ohio, 379 U.S. 89 (1964)An officer’s subjective good faith is not the test. If it were, Fourth Amendment protection would exist only at the discretion of the police.
- United States v. Sokolow, 490 U.S. 1 (1989)Reasonable suspicion is based on the totality of the circumstances and is a lesser burden than probable cause.
- Penal Code Sec. 2.01 · Proof Beyond a Reasonable DoubtAll persons are presumed innocent. Being arrested, confined, indicted or charged gives rise to no inference of guilt at trial.
- Penal Code Sec. 2.02 · ExceptionWhen a statute labels something an exception, the prosecutor must negate it in the charge and disprove it beyond a reasonable doubt.
- Penal Code Sec. 1.07(a)(42) · Reasonable BeliefA belief that would be held by an ordinary and prudent man in the same circumstances as the actor.
On the exam Expect a question that gives you a level of proof and asks what it allows, or gives you an action and asks what level it requires.
A hunch or feeling of intuition is called .
Reasonable suspicion is based on the and is a lesser burden than probable cause.
Under Penal Code 2.01, a person may be convicted only if each element of the offense is proved .
The three kinds of police and citizen contact
Every contact between an officer and a person falls into one of three categories, and each category needs a different level of proof.
In a consensual encounter the person is free to refuse to identify themselves, refuse to answer, and walk away. In an investigative detention the person is temporarily seized, which requires reasonable suspicion of criminal activity. In an arrest the person is taken into custody to be charged, which requires probable cause.
- Consensual encounter
- No seizure. The officer may approach and ask questions. The person may decline and leave. Requires nothing.
- Investigative stop or detention
- A temporary seizure for investigation. Requires reasonable suspicion.
- Arrest
- Custody for the purpose of charging a crime. Requires probable cause.
- Florida v. Royer, 460 U.S. 491 (1983)Officers may approach and question a person, who remains free to refuse and walk away.
- Terry v. Ohio, 392 U.S. 1 (1968)A temporary investigative detention is lawful on reasonable suspicion of criminal activity.
- United States v. Mendenhall, 446 U.S. 544 (1980)The curriculum’s authority for when a contact becomes a seizure of the person.
On the exam Match the case to the contact: Royer goes with consensual encounters, Terry with detentions.
A temporary seizure of a person for investigation requires .

What you can do with mere suspicion
Mere suspicion gives you no power over the person, but it does not mean you do nothing. The goal at this stage is to gather articulable facts that raise what you know to reasonable suspicion or probable cause.
You may run a computer check on a license plate. You may conduct surveillance and watch for more facts. You may start a consensual encounter, as long as you understand the person does not have to identify themselves or answer, and may walk away at any time.
On the exam The wrong answers here are always some form of detaining, frisking or demanding ID. None of those are available on a hunch.
With mere suspicion, an officer may run a computer check of a .
The officer’s objective at this stage is to obtain facts and circumstances that rise to reasonable suspicion or probable cause.
