1: increasing protections for persons accused of crimes

Explanation:

Mapp resulted in the use of evidence found by unreasonable search and seizure being inadmissible in court as a violation of the 4th amendment.

Gideon resulted in the legal mandate of the courts providing legal counsel to defendents who cannot afford to hire representation.

Miranda resulted in the Miranda rights that are read to one when being arrested, such as you have the right to remain silent, and confessions given under interrogation without being told they can consult legal counsel, will not be usable in court
