My father is the owner/operator of a hotel and recently police officers have been hassling guests during their patrols. Often times officers will handcuff guests and question them in the back of the squad car and even search their rooms without permission from my father. The customers are always let go after questioning but the experience has made customers demand their money back which is bad for business. Are the searches and questioning legal? My father has already filed complaints against the department but isn't getting anywhere. Should he contact a lawyer?
