In the context of criminal law, what is meant by the phrase, "Hunches are never enough"?
In the context of criminal law, hunches are not enough because more concrete proof is needed in order to do things like securing a warrant or gaining a conviction.
When police are investigating a crime, it is not sufficient for them to have hunches. They cannot get a warrant because they have a hunch they would find evidence of illegal activity in a given house. Instead, they need to have probable cause that can be examined objectively by a judge.
When a case is brought to trial, it is not enough to have a hunch about the defendant's guilt. The prosecution must have enough evidence to prove the case beyond a reasonable doubt.
Thus, in the context of criminal law, this phrase means that objective evidence is needed and that hunches are not sufficient.
