If looks could kill, this one would have literally killed some ill-informed people

Earlier I had written about some tourists ignoring the personal space of the tribes when at Hornbill Festival. Here is another example of it. The guy in the image is unhappy that some men were grabbing his tribe girl only to get some selfies. 
There are various questions that came to my mind when I saw this happen-
Is troubling them worth the selfies?
What are these tourists trying to prove or achieve by the images?
How would they react if someone was to grab hold of a lady in their family just for a picture?
