Which of the following requires a warrant for a routine arrest?

For a routine arrest in a private residence, a warrant is indeed required. The Fourth Amendment of the U.S. Constitution protects individuals from unreasonable searches and seizures, and this protection extends to one's home. In general, law enforcement must obtain a warrant before entering a private residence to make an arrest, unless exigent circumstances are present.

When it comes to arrests made in public places, there is an expectation of less privacy, which allows officers to arrest individuals without a warrant under certain conditions. Similarly, arrests for felonies typically do not necessitate a warrant if they are made in a public space where the officer has probable cause to believe a crime has been committed. Arrests during daylight do not inherently require a warrant; the time of day does not usually impact the necessity for a warrant. Therefore, the requirement for a warrant stems specifically from the right to privacy within one's home.
