Seriously, did you even read the statute you, yourself posted, junior? Since you say you have to give them the option to put the tv down, step away from you and exit, I am assuming that you are speaking of a home burglary. If you will actually read exception (a) above you will read that the option to retreat DOES NOT APPLY in a person's dwelling place!
Also, in the case of a street mugging, the duty to retreat only exists if it can done IN COMPLETE SAFETY. If the perpetrator has the ability to pursue, then the victim cannot retreat IN COMPLETE SAFETY can they? Where the duty to retreat would come into play is if I am attacked, and I defend myself, and I render the perp unconscious, or injure the perp to such an extent that they can't pursue, than I must stop my defensive actions and retreat. But if they retain the ability to pursue, or to shoot at me, the game is still on.
As far as the ability to detain a criminal, we would have to look at Maine's citizen arrest statutes....
Really, I would suggest that you pay a good criminal defense lawyer $200 to spend an hour with them and get a real education on the self-defense statutes.
PS - You most certainly CAN legally detain the perp in Maine!

Also, by the way, junior, did you know that a private party can use deadly force in effecting a citizen's arrest?
