What type of evidence is needed for sufficient reason to detain but not arrest in field identification?

The concept of "reasonable suspicion" is key in the context of detaining an individual for field identification. Reasonable suspicion is a legal standard that is lower than probable cause and allows law enforcement officers to briefly detain a person for questioning when they have specific and articulable facts suggesting that a person may be involved in criminal activity.

In situations such as field identifications, officers may not have enough evidence to make an arrest, which requires probable cause. Instead, they may observe behavior or circumstances that raise reasonable suspicion, which is sufficient to detain a person for a limited period to investigate further. This standard is meant to balance individual rights with the need for police to maintain public safety.

Probable cause, required for an arrest, means there must be enough evidence to believe that a crime has been committed by the person. Beyond reasonable doubt is an even higher standard, typically used in criminal trials to determine guilt, while direct evidence refers to evidence that directly establishes a fact without the need for inference. These standards are not applicable for the scenario described in the question regarding field identification.
