How much evidence is needed to get a warrant?

To get a warrant, police need to establish "**probable cause," meaning a judge must be convinced there's a fair probability a crime occurred and evidence will be found, based on specific facts in a sworn affidavit, not just suspicion. This affidavit details evidence like witness statements, officer observations, or reliable informant tips, describing precisely what and where to search or who to arrest. The standard is lower than "beyond a reasonable doubt" for conviction but requires more than a hunch.
