Question

What might qualify as exigent circumstances for purposes of seizing an item?


The item is established as potentially exculpatory.

The item is clearly illegal.

The item is potentially dangerous.

The evidence will probably be destroyed unless an immediate seizure is made.

Answer 1

Exigent circumstances for a warrantless seizure generally require an immediate, concrete risk that justifies bypassing the warrant requirement — e.g., risk to safety or imminent loss of evidence. Of your four choices:

- The item is potentially dangerous — Yes. A risk to officer or public safety (weapons, explosives, etc.) is a classic exigency (see Warden v. Hayden/hot pursuit and related safety-based exigency rulings).
- The evidence will probably be destroyed unless an immediate seizure is made — Yes. Imminent destruction or dispersal of evidence is a textbook exigency (see Schmerber/Missouri v. McNeely principles about exigent needs to avoid loss of evidence).
- The item is clearly illegal — Not by itself an exigent circumstance. If the incriminating nature is immediately apparent from a lawful vantage point, the plain‑view doctrine permits seizure without a warrant, but that’s a different justification than exigency.
- The item is established as potentially exculpatory — No. The possibility that an item helps the defense does not create exigent circumstances to allow a warrantless government seizure; due‑process concerns rather constrain government seizure of exculpatory material.

Also note: exigency cannot be manufactured by police conduct (Kentucky v. King).
