Why do convicted felons wear bullet proof vests in court?

Convicted felons may wear bulletproof vests in court primarily for their safety due to the high tensions that can arise from their convictions and potential threats from victims or their families. Courtrooms can be charged environments where emotions run high, and the presence of security measures like bulletproof vests helps ensure protection against any possible violence. Additionally, in high-profile cases, the risk of attacks may necessitate extra precautions for the defendant's safety.
