What does the ruling in Beck v. Ohio state about arrests made without probable cause?

The ruling in Beck v. Ohio established that arrests made without probable cause are not valid and the evidence obtained as a result of such arrests is inadmissible in court. This case emphasizes the principle that law enforcement must have probable cause to make an arrest; otherwise, the constitutional rights of individuals are violated. The exclusionary rule, which is rooted in the Fourth Amendment, prevents evidence obtained through unlawful means, such as an arrest lacking probable cause, from being used in criminal prosecutions. Therefore, any evidence found as a result of an invalid arrest cannot be admissible in court, supporting the notion that an individual’s rights must be protected against arbitrary and unlawful actions by law enforcement.
