It was repeatedly written in the press about conflicts with security in shopping centers that require them to go into the utility room and where they search your belongings. At the same time, it was repeatedly explained that the security does not even have the right to detain a person, and if strictly according to the law, in the case of a stubborn buyer, the guard can only run after him and exhort, hoping that the police will arrive in time. Is it so? How is the protection action qualified if they are still trying to physically stop the buyer, and how are the buyer actions qualified if he responds the same to this physical effect? Does this mean that if they grab my hand, I can rightfully put the grabber on the floor?
