Which of the following is classified as a restricted use informant?

A restricted use informant generally refers to a category of informants who may be limited in their capacity to provide accurate or reliable information due to specific characteristics or circumstances. In this case, individuals under the age of 18 are considered restricted use informants primarily because of their developmental stage and potential susceptibility to coercion or manipulation. Minors may not possess the same level of maturity or understanding as adults, which can impact their reliability as informants.

The other options do not inherently restrict the use of the informant in the same way. An individual with one felony conviction does not automatically imply they are unreliable as an informant; their past may have no bearing on the information they provide. An informant who provides information willingly, despite their motives, doesn't determine the level of trustworthiness or the restrictions placed upon them. A cooperating business owner, while potentially valuable, does not fit the profile of restricted use based solely on their cooperation or occupation. Therefore, identifying individuals under the age of 18 captures the essence of a restricted use informant due to the vulnerabilities associated with age.
