I like correcting people
"Under UK law, that footage is classed as child pornography"
No, they could even be completely nude nudists on a beach with their families and it still wouldn't be classed as that.
UK law is very specific as to when any image is classed as pornographic. It has to have a sexual content. I dont think those teens rushing out of the school were in a sexual position. I think they were running for their lives.
By your definition, you see that famous picture of Phan Thi Kim Phuc as porn?
Wow, how do you handle walking around a church with cherubs on the wall?
If you are going to make a statement like this, do your research first.
