Coordinate with the nurse/s and be on the same page with him or her as to what conditions would be beneficial or harmful for the overall well-being of the principal. Be aware of certain types of foods, medication, and environmental factors that may bring about allergies or adverse reactions and be sure to steer clear of such items.
With his medical condition and the impending court hearing, the principal is under tremendous stress, as it is. It is important to consider these factors in looking out for the principal. Carelessness in planning and giving out unnecessary information may just cause the principal undue stress that would aggravate the already delicate situation. Always keep in mind that there are certain things without the knowledge of which the principal is better off.
Coordinate with the lawyer and come up plans that fit the need of the principal within the limits of the law at the moment. Since the police are not providing any protection, constantly communicate with principal's lawyer to update oneself with the legal extent up to which protection can be provided for the principal.
