This just happened last night. My daughter's brother-in-law woke up in the middle of the night from noise in the house, went out and found a large man in his living room. Burglar didn't stop on command, instead came at him and started using pepper spray, so my in-law emptied his 5 shot 38 into him, killing him. My initial reaction when I heard the news was "hey good for him awesome job." Then I heard about how he was handling it. Something we don't think of in discussions about use of lethal force is the emotional toll it takes, this poor guy is a wreck, feels awful, is on an emotional roller coaster of after shock/fear/anxiety/worry/2nd guessing about his justification, etc, not to mention the horror of having a body riddled with holes in your living room. He spent the next day drinking heavily and fretting over having killed a man. He's a mess, it'll be awhile before he gets over it. Just something to think about.
