I think courts would be very reluctant to convict anyone on unlawful detainment if the facts would have allowed for the legal use of deadly force.

Taking away a legal alternative other than deadly force would seem to strengthen a defense against an a charge of unlawfully shooting an intruder, since you really would have no other legal option available (assuming that fleeing is not feasible and the BG refuses to just leave peacefully).

Then again, IANAL.
