Cutting Cops Too Much Slack, Wayne A. Logan

Scholarly Publications

Police officers can make mistakes, which, for better or worse, the U.S. Supreme Court has often seen fit to forgive. Police, for instance, can make mistakes of fact when assessing whether circumstances justify the seizure of an individual or search of a residence; they can even be mistaken about the identity of those they arrest. This essay examines yet another, arguably more significant context where police mistakes are forgiven: when they seize a person based on their misunderstanding of what a law prohibits.

The federal government and most states have enacted statutes that permit or direct the testing of those convicted of at least certain crimes. Courts have almost universally approved such testing, rejecting arguments that obtaining and using such evidence violates the Fourth Amendment.

More recently governments have enacted laws permitting or directing the …

The Death Penalty On The Streets: What The Eighth Amendment Can Teach About Regulating Police Use Of Force, Jelani Jefferson Exum

Faculty Publications

(Excerpt)

The use of force by police officers has traditionally been analyzed through the lens of Fourth Amendment reasonableness. The Supreme Court has decided that the proper question regarding the excessiveness of police force is whether the police officer acted as a reasonable law enforcement officer. When that police force is fatal — what this Article deems the death penalty on the streets — the legal question is the same, leaving us with an analysis that requires a heavy reliance on the officer's version of events and a host of disagreement on what constitutes appropriate police action. Reasonable minds can, …
