Harry Blackmun,
Graham v. Connor — Concurring Opinion
“ I expect that the use of force that is not demonstrably unreasonable under the Fourth Amendment only rarely will raise substantive due process concerns. But until I am faced with a case in which that question is squarely raised, and its merits are subjected to adversary presentation, I do not join in foreclosing the use of substantive due process analysis in prearrest cases. ”
