What is the test for a warrantless search?

Defendant has cited the case of Hood v. Superior Court of Los Angeles County, 220 Cal.App.2d 242, 33 Cal.Rptr. 782 in support of his contention that there is insufficient evidence to support a finding of probable cause to arrest and so to legitimize a warrantless search. Hood is not sufficiently comparable to the instant [6 Cal.App.3d 77] case to carry any persuasive effect; there was no reliance on the informant, whose reliability the prosecution never sought to establish.
