It definitely depends on the state and store policy.
A Walmart in AZ has sent gigantic bouncers after me to detain me on suspicion of shoplifting a $5 bag of cat litter. In my state they are allowed to kidnap/imprison you until police arrive if they have 'reasonable suspicion' you're in the act of shoplifting, so yeah have fun guessing whether the guy with the walmart badge is actually security or just a rapist.
