Martin/Zimmerman thread got me thinking. (Please keep comments specific to that case in that thread.)
What defines self defense? Do you agree with the legal definition?
When can you claim it? When can you not?
What is the bare minimum in "harm" for it to be justified? Threat? Actual physical harm? Significant physical harm?
Examples for discussion:
Do you think the Uncle would have been justified if after he caught the man he had shot him?
If someone breaks into your home, is there a time when deadly force isn't justified?
If someone steals your car, can you use deadly force to protect your personal property? What if you were in it at the time?
