the fourth amendment protects the people from the governments or law enforcements unnecessary search and seizure. the termsearch can refer to many actions: a search of a suspects home or computer, a dna test or a police officer frisking citizens. seizure is when the government takes an individuals possession. items that the government seizes can be used as evidence in a case against a suspect. seizure also used to refer the government taking possession of an individual.
the main principle of this amendment is that any citizen may be accused of a crime by the state, so the state must ensure their legal protection. the amendment prevents the police and courts from using illegally obtained evidence. it allows for limits on police when they are investigating a crime. but there are certain types of searches that citizens arent protected against by the fourth amendment. for instance, schools can search students lockers for evidence of a crime even though a student may consider that locker their property

c protects students property on school grounds.
