If they tase and pepper spray you before asking you to leave, you go to the local magistrate and take out assault charges against the individual, and then sue the company.

(It’s still illegal to assault someone after telling them to leave, but they have more options. They could get creative then, detain you on suspicion of shoplifting. But they can’t physically hold you. What they would do is tell you that if you walk, they will charge you with some bullshit. But if you stay, they will just ban you from the store and make it official. The risk there is, as soon as the cops show up, they can say that they asked you to leave an hour ago and you’re still there. If it’s me, I’m not sticking around, nor providing them with identification, and if they try to lay hands, I will defend myself. But I’m also not a vandal.)
