"The 'theory of a crime' is a proposed explanation by the detective of what actually happened. Any theory must be reevaluated as new facts are discovered, which modify or are at variance with the facts serving as basis for the initial theory. The initial theory and its modifications serve to aid the detective in the analysis of the evidence and in the determination of how each piece of direct, real, or substantial evidence is linked to the crime. It aids in establishing the sequence of events and in checking actions and accounting for intervals of time. During the reconstruction of the crime and during the formulation of proposed explanations, the detective must constantly distinguish between relevant and irrelevant evidence." Which one of the following statements is most fully based on and supported by the selection?
A
The sequence of events can be determined by a careful initial theory.
B
The theory of a crime should be used as a basis for testing the truth of statements by witnesses.
C
The relevancy or irrelevancy of new evidence should be determined by how it fits the proposed theory.
D
A proposed theory should be amended when necessary to account for new, substantial facts and evidence.
E
All facts, disclosed as a result of the theory, must be compared with the statements of witnesses and suspects. Correct Answer: A proposed theory should be amended when necessary to account for new, substantial facts and evidence.
"Where constitutional rights are invaded by an unreasonable search and seizure, the United States Supreme Court does not permit use of the evidence obtained by such search, and would further hold an arrest based thereon to be improper. However, it may be noted that this result follows only where defendant's constitutional rights have been invaded; not merely from alleged illegality of securing evidence. In other words, evidence is so excluded only where there has been a violation of the constitution, not merely where there has been a violation of law." Which one of the following choices is most fully supported by the above paragraph?
A
Evidence secured by a violation of the law is inadmissible in court and can not be the basis of a proper arrest.
B
The doctrine of the exclusion of evidence illegally obtained is confined to those cases of violation of some constitutional right of the defendant.
C
The courts have a discretion to exclude evidence, the admission of which is not unconstitutional, because it was unethically secured.
D
The right of a police officer to make an arrest and to use evidence in court may depend on whether he has violated the law.
E
An improper arrest is defined as one that is based on an unreasonable search and seizure, which violates the defendant's constitutional rights. Correct Answer: The doctrine of the exclusion of evidence illegally obtained is confined to those cases of violation of some constitutional right of the defendant
