Answer:
Arresting a suspect without reading their Miranda rights
Step-by-step explanation:
Given that Miranda warning is a form of warning given to criminal suspects notifying them of their right of not saying anything if they wish to do so; that is, they have the right not to answer questions to law enforcement until they have their lawyer.
Hence, under the United States law it is established that in a situation whereby law officers or enforcers question a suspect in custody without notifying him of Miranda warning, such answer is deemed to be forced, and does not follow due process, thereby will not hold against the suspect in a court of law.
Hence, in this case, the correct answer is "Arresting a suspect without reading their Miranda rights"
