What type of evidence might be affected by the exclusionary rule?

The correct choice is that evidence acquired through illegal searches and seizures might be affected by the exclusionary rule. The exclusionary rule is a legal principle that prohibits the use of evidence obtained in violation of a person's constitutional rights, particularly under the Fourth Amendment, which protects against unreasonable searches and seizures. If law enforcement officers obtain evidence without a proper warrant, probable cause, or other lawful justification, that evidence cannot be used in court against an individual.

In contrast, evidence obtained with proper consent is considered legally sound, meaning it would not be impacted by the exclusionary rule. Similarly, evidential footage from security cameras that is collected with appropriate legal authority or cooperation from the parties involved would also not fall under the scope of the exclusionary rule. Lastly, witness testimonies collected during an arrest are typically not excluded based on the exclusionary rule unless they are directly tied to tainted evidence. Thus, the focus is on the legality of the method of obtaining evidence, reinforcing the concept that evidence improperly obtained cannot be used to prosecute individuals.
