CCJS 234 Criminal Procedure and Evidence is a University of Maryland Global Campus course on the rules that govern how police investigate and how cases are tried.
UMGC describes it as a study of the general principles of criminal procedure, emphasizing the history and evolution of criminal procedure in the United States.
Fundamental components include privacy, reasonableness, probable cause, search and seizure, search warrants, interrogations and the trial process. Topics also cover the connections between the law, the criminal justice process, criminal procedure and evidence.
Where CCJS 230 asks what is a crime, CCJS 234 asks how the state may prove it. Students find the case law dense, and scenarios require applying exceptions precisely.

What CCJS 234 Covers
| Topic | Key questions |
|---|---|
| Privacy | When does a person have a reasonable expectation of privacy? |
| Reasonableness and probable cause | What level of suspicion justifies police action? |
| Search and seizure | What counts as a search or seizure, and when is it lawful? |

Key Cases and Rules
| Case | Rule |
|---|---|
| Mapp v. Ohio (1961) | The exclusionary rule applies to the states |
| Katz v. United States (1967) | The Fourth Amendment protects reasonable expectations of privacy |
| Terry v. Ohio (1968) | Brief stops and frisks need reasonable suspicion |
| Miranda v. Arizona (1966) | Warnings required before custodial interrogation |
| Gideon v. Wainwright (1963) | States must provide counsel to defendants who cannot afford it in felony cases |
| Riley v. California (2014) | Police generally need a warrant to search a cell phone seized at arrest |
Warrant Exceptions
Warrantless searches are presumed unreasonable, but courts recognize exceptions: consent, search incident to lawful arrest, plain view, exigent circumstances and the automobile exception (from Carroll v. United States, 1925), which allows searching a vehicle with probable cause.
Example scenario: An officer stops a car for speeding and smells cannabis smoke in a state where possession is illegal. She searches the boot and finds stolen goods. Analysis: the stop is lawful (traffic violation). Under the automobile exception, the question is whether the smell gave probable cause to believe evidence of a crime was in the car; in many jurisdictions it has, though state law changes on cannabis are altering this. If probable cause existed, the search is lawful and the goods are admissible; if not, the exclusionary rule may apply.
Evidence at Trial
Evidence must be relevant and not barred by a rule of exclusion. Hearsay (an out-of-court statement offered to prove its truth) is generally inadmissible, subject to many exceptions.
Illegally obtained evidence may be excluded, along with derivative evidence ("fruit of the poisonous tree"), unless an exception such as inevitable discovery or good faith applies.
The prosecution must prove guilt beyond a reasonable doubt, and the defendant has rights to counsel, to confront witnesses and to a jury trial for serious offenses.
Interrogations and Confessions
Confessions must be voluntary under the Due Process Clause, and Miranda adds procedural protection during custodial interrogation. Custody means a reasonable person would not feel free to leave; interrogation includes express questioning and actions police should know are likely to draw an incriminating response.
Once a suspect clearly asks for a lawyer, questioning must stop. A suspect can waive Miranda rights, but the waiver must be knowing, intelligent and voluntary.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Search scenario | Applying the Fourth Amendment | Was it a search? Warrant? Exception? Remedy? |
| Interrogation scenario | Applying Miranda | Custody plus interrogation means warnings |
| Case brief | Reading case law | Facts, issue, holding, reasoning |
| Policy discussion | Evolution of procedure | Link cases to changing views on rights |
Where Students Get Stuck
- Reasonable suspicion versus probable cause. Stops need the first; arrests and most searches need the second.
- Miranda's triggers. Warnings apply to custodial interrogation, not every police conversation.
- Missing the remedy. After finding a violation, say what happens to the evidence.
- Outdated law. Digital privacy cases are changing quickly; use current sources.
Study Tips for CCJS 234
- Use a decision tree for search questions: search, warrant, exception, remedy.
- Brief each major case on one card: facts, issue, holding, significance.
- Read Supreme Court opinions' syllabi for an official summary.
- Practice with news stories about searches and interrogations.
