Final answer:
In the legal context, the question pertains to assessing the credibility of informants' information. Even if the information initially lacks credibility, the police can strengthen it with corroborating evidence.
Step-by-step explanation:
In the context of the law, the question refers to the veracity prong and basis-of-knowledge prong in relation to informants' information. When police receive information from an informant, they assess its credibility by considering whether the information is trustworthy and if the informant has a reliable source of knowledge. Even if the informant's information initially fails these criteria, the police may still be able to strengthen it by providing additional corroborating evidence.
