Once you steal property that doesn’t belong to you, you give up certain rights. Like it or not, in my state a merchant can detain with force. As I used to say, you can fight but you’ll just go to jail tired and catch more charges. Also, if you have stolen property and then use attacking force in an effort to get away, you have elevated a misdemeanor petit theft into a felony robbery. Instead of probation, you are looking at 5-10 years. I really don’t recommend fighting store security in an effort to get away. It’s super easy to elevate a charge to robbery.
