Final answer:
In exigent circumstances, a thorough search can be conducted without waiting for a search warrant. Officers can seize evidence found during the search, not just plain-view evidence.
Step-by-step explanation:
In exigent circumstances, once police officers have made an entry, they are not required to immediately exit. Instead, a thorough search can be conducted. Awaiting a search warrant is not necessary in exigent circumstances as it may result in the destruction or tampering of evidence. Additionally, officers can seize not only plain-view evidence but also any evidence that is discovered during the search.
