It seems highly unlikely that a 12-year-old girl could have entered such a strictly regulated country without assistance. Those accepting this scenario might be misinformed and fooled at the same time
You're saying this 12 year old didn't run away from home, travel from India to UAE alone without proper visa/passport, and then sneak into this UN event with the sign hidden in her socks? Shit, thank God you're here to clarify that.
Of course she had support from her parents and someone who was able to get her in the door. Most effective acts of protest are heavily organized. That doesn't detract from anything.
