Potter Stewart,
Coolidge v. New Hampshire — Opinion of the Court
“ Where the police act without an arrest warrant, the suspect may argue that an arrest warrant was necessary, that there was no probable cause to arrest, [34] or that even if the arrest was valid, the search and seizure went beyond permissible limits. [35] Perhaps because each of these lines of attack offers a plethora of litigable issues, the more fundamental question of when the police may arrest a man in his house without a warrant has been little considered in the federal courts. ”
