It's often posted here and in threads in General and Legal that Castle Doctrine Laws are an automatic free pass if you should shoot someone in your residence. Everyone who thinks that should read this article: http://www.stltoday.com/news/local/...cle_e5733da4-9156-11e0-bec5-0019bb30f31a.html You might notice that the incident occurred in April and on June 7 they were cleared and the shooting was deemed justified under the Castle Doctrine Law. The two were arrested, had to post bond, hire attorneys and worry about their future for 2 months while the investigation was conducted and the prosecutors decided that it was in fact a justified shooting. The use of deadly force is always a very serious thing and you shouldn't expect a pat on the back from the authorities if you have to use deadly force. You can expect a thorough investigation and maybe to be arrested if things don't immediately look like a clear cut case of self defense. I suspect that the woman's prior relationship with the deceased had something to do with the investigation. Even though she had an order of protection against the deceased many couples get them when they are angry with each other and then when they reconcile ignore it, until they are angry again then protected party often wants it enforced.
