In the context of criminal records, the term "reasonable grounds" refers to:

The term "reasonable grounds" in the context of criminal records is often interpreted as a standard for establishing a basis for suspicion that can justify certain actions, such as investigatory stops or arrests. It involves having a justifiable basis for believing that a particular individual was involved in criminal activity, usually based on facts or circumstances that can be articulated and are more than mere speculation or hunches.

This concept emphasizes that reasonable grounds must stem from specific, observable facts or previous knowledge rather than vague impressions. Suspicion based on previous knowledge can include things like past criminal behavior, witness testimonies, or other relevant information that can lead law enforcement to reasonably suspect that someone may be involved in a crime.

In contrast, the other options do not accurately represent what constitutes "reasonable grounds." Grounds to arrest any suspect suggests a lack of specificity that isn't aligned with the requirement for a justifiable basis. Evidence beyond a reasonable doubt refers to a legal standard used in criminal trials, which is much stricter than what is required to establish reasonable grounds. Common knowledge about the crime does not necessarily provide the necessary specific suspicion needed to justify actions taken by law enforcement.
