Did the people know each other?
Were drugs involved?
Who were the other people present besides the shooter?
Your social life may be more interesting than mine, however, whenever I see "2:00AM," "4 People," and all in a rather "bad neighborhood," I wouldn't take sides until the coppers sort it out. Notice also "uninvited," Not "Broke in."
Caveat lector.
After a review of the thread, I still fail to see anything in my replies that I should apologize for. However, if you will kindly point out where I violated your apparently highly refined standard for acceptable comments I will apologize anyway.
Is that satisfactory, or should I just go ahead and apologize here and now for any and all posting faux pas that I may have committed since I came into this world uninvited?
