Demonstrate a critical thought process about below: Emergency searches (also called exigent circumstance searches) are based on the idea that it's sometimes impractical (even dangerous) to require officers to obtain warrants before they search. The danger might be ( 1) to officers' safety, justifying frisks or pat downs for weapons (Chapter 4); (2) that suspects or others might destroy evidence during the time it takes to get a search warrant; (3) that fleeing felons might escape while officers are trying to obtain search warrants; or (4) that individuals in the community are in immedi- ate danger. Because we've already examined frisks, in which officers' reasonable suspicion that a lawfully stopped suspect is armed justifies a pat down for weapons (Chapter 4), we won't repeat that discussion here. Let's interrogate three other types of emergencies.
