What is assessed in the second prong of the Aguilar-Spinelli Test?

The second prong of the Aguilar-Spinelli Test specifically focuses on the reliability of the informer's knowledge about the information they provide regarding criminal activity. This aspect assesses whether the informant has firsthand knowledge of the events they report and whether the information is deemed credible. This requirement ensures that law enforcement relies not merely on vague or unverified tips but rather on information grounded in the informant's direct experience or observations.

Evaluating the reliability of the informant's knowledge is crucial for establishing probable cause for a search or seizure. If the informant can demonstrate a reliable basis for their assertions—such as having previously provided accurate information or being a participant in the observed criminal behavior—this strengthens the case for law enforcement to act based on that information.

Understanding the second prong is essential in the broader context of ensuring that the rights of individuals are protected while also allowing law enforcement agencies to effectively address criminal activities using credible information.
