For my money, since I can not see the end of the barrel, the picture is taken from her left, it appears to me that the gun may be pointed to the left of the PH.
As far as trusting someone to get my back, it can be man, woman or the green chick that Wm. Shatner nails in the old Star Trek show, but I aint trusting anyone to cover my back that hasn't already showed me they would in a situation in which I needed my back covered. I've been in lots of situations where people reacted totally differently than most people would have guessed. Some positively and some negatively. But it's happened both ways with both men and women, so I aint judging based on gender. I'm better off believing I gotta cover my own back, until I look back and see someone else covering it, as opposed to believing they are there. People will cut and run that you would never believe would have.
