EDIT: if you’re going to change your post, common courtesy is to put an edit note. You changed your bolded “will happen” to “may happen”

Kinda had to because you misintepreted it. Will happen has a probability tied to it.

When asked to quantify the degree of certainty represented by the phrase “probable cause,” 166 federal judges gave, as an average response, 45.78%. C.M.A McCauliff, Burdens of Proof: Degrees of Belief, Quanta of Evidence, or Constitutional Guarantees?, 35 VAND. L. REV. 1293, 1327 (1982). They also equated reasonable suspicion with a 31.34% level of certainty

Seriously, your personal ideas of reliabilty are sort of irrelevant to what can be used to establish probable cause and get a warrant legally.
