What obligation is there for police to find and arrest false 911 callers?
<p><a href="https://abcnews.go.com/US/black-oklahoma-man-held-gunpoint-police-handcuffed-false/story?id=78440609&amp;cid=clicksource_4380645_1_heads_hero_live_headlines_hed" rel="nofollow noreferrer">Oklahoma man held at gunpoint by police, handcuffed after false 911 call</a></p>
<p>Given that 911 calls are recorded and the phone number is logged, I would expect that a motivated detective to quickly ID a suspect.</p>
<p>Does said police department have any obligation to ID, investigate and detain / arrest the false caller?</p>

<p>No. See <em>Castle Rock v. Gonzales</em>, <a href="https://www.oyez.org/cases/2004/04-278" rel="noreferrer">545 US 748</a> (2005).</p>
<p>Usually, police do investigate, but that is a matter of department policy and political expectations, not a legal obligation to do so.</p>
