ANSWER:

Although there might appear to be some sort of benefit from spreading such videos, I believe that the cons far exceed the pros. It violates the dignity of the injured and oppressed by showing their faces! It makes people accustomed to such atrocities and after a while, watch it normally while having lunch without being affected by it. It also helps in building a feeling of fear and intimidation from the enemies of Allah when seeing such footage. 

Respected Sheikh,I hope this message finds you in the best state of Emaan. Recently our brothers got targeted in NewZealand in which a shooter recorded himself entering the mosque and firing at Muslims. The video has been circling around the social media. Is it ok for Muslims to spread such graphic videos which portrays Muslims being killed.
