Kingsley makes the gray zone a lot less dangerous. Under the decision, any “objectively unreasonable” use of force against detainees is unconstitutional. Just as importantly, the court reaffirmed that “pretrial detainees (unlike convicted prisoners) cannot be punished at all.” In other words, police cannot penalize a suspect, much less abuse him, merely because they believe he’s committed a crime.
