Final answer:
It is true that individuals in witness protection may be allowed to wear body armor for their safety and security, as the primary goal of these programs is to protect witnesses from potential harm.
Step-by-step explanation:
It is true that a person participating in a witness protection program may be allowed to wear body armor. Witness protection programs are designed to ensure the safety of individuals who may be at risk due to their testimony or cooperation with law enforcement. Given that the primary purpose of such programs is to protect witnesses from potential harm, the use of body armor could be considered a reasonable safety measure. Though policies may vary by jurisdiction and specific circumstances, the protection of witnesses is a priority, and therefore, accommodative measures like body armor could be permitted for their safety and security.
