"Castle doctrine" bill in AZ
The Arizona Senate unanimously passed SB 1145, which has two main effects: (1) "no retreat" if defending house or auto (although AZ doesn't have a retreat requirement anyway) and (2) use of deadly force is presumed to be justified if the other person forcefully and unlawfully entered a home or vehicle. The latter is a change in the law which, as I recall, requires a defendant to prove the defense of justification, and by a preponderance of the evidence. Word is that in the House there may be an attempt to remove the latter section. If you want to give the legislature your feelings, you can find your legislators here.
