Pedro and his brother are both given a glass of punch at a birthday party. pedro's punch is in a short and wide glass while his brother's punch is in a tall and thin glass. pedro believes that he has less punch than his brother. according to piaget, pedro has not yet developed

Pedro has not yet developed his concrete operational stage in which is laid at piaget’s theory of moral development. The concrete operational stage is where an individual is likely to develop logical thought in which we could see in the scenario above that Pedro is not yet on that stage yet.

the fourth amendment protects:

"the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."  

so this would mean the denial to search and seizure without warrant or permission.
