Eh tricky. Not sure I would call it 1st degree unless the guard was planning on shooting the guy ahead of time. Sounds more like a heat of the moment confrontation, although I suppose they could anticipate knocking it down to 2nd degree.

Edit: Cool getting downvoted by a bunch of folks who are acting like I think it was a justified killing or something. Whatever though.
