What type of evidence must an officer have to conduct a search under the concept of probable cause?

In order to conduct a search under the concept of probable cause, an officer must have evidence that is credible and trustworthy. This includes information based on reliable sources, which can be corroborated and has a basis in fact. When evidence is gathered from reliable informants or through verifiable means, it strengthens the case for establishing probable cause.

While a hunch or direct observation of a crime can contribute to probable cause, they alone do not suffice without supporting evidence or reasonable indicators that substantiate the claim. A hunch lacks concrete foundation and may not meet the legal standards necessary for a search. Direct observation, while valuable, must be adequately supported by other evidence or context to fully establish probable cause.

Thus, having information based on reliable sources is the most effective and necessary component to fulfill the requirement of probable cause for a lawful search.
