Final answer:
The scope of the search is limited to a pat down of outer items unless there is reasonable suspicion. The Supreme Court found the intrusive search on Savanna to be excessive and unjustified according to Fourth Amendment protections.
Step-by-step explanation:
The scope of the search mentioned in the question is limited to a pat down of outer clothing, containers, and property being carried by the subject. As established in Terry v. Ohio, police have the authority to conduct a stop and frisk without violating the Fourth Amendment if they have reasonable suspicion that a crime has been or is about to be committed, and that the person stopped is armed and dangerous.
As for the case of Savanna, the Supreme Court concluded that a search of her belongings and pockets was justified under the premises of reasonable suspicion.
However, the invasive search beneath her clothing was deemed unreasonable since there was no indication that she was concealing contraband in such a manner, making it an unjustified search and seizure under the Fourth Amendment protections.
