What determines if evidence is strong enough to uphold a arrest?

Answer 1

probable cause

Answer 2

The strength of evidence necessary to uphold an arrest varies depending on the jurisdiction and legal standards in place. Generally, evidence must meet a probable cause standard, meaning that there must be a reasonable basis to believe that a crime has been committed and the person to be arrested is responsible. Factors such as witness statements, physical evidence, and the credibility of the evidence can all contribute to determining if evidence is strong enough to uphold an arrest. Ultimately, it is up to a judge or grand jury to evaluate the evidence and decide if it is strong enough to justify an arrest.
