Of course there's so much questions to answer. And secondly, I like the way they handle the situation because sometimes some youth would burn or kill the person without confirming whether he's a suspect or not. I think they should take him to police station for proper investigation. And they need to question his work and his way about just like you said.

Secondly, sometimes you need to be careful when taking pictures depending of what is happening. Because you might end up in trouble(Talking from experience). Thank you for sharing this event with us. Good luck.
