This is just crazy!! If I was walking in a mall and saw what I thought was Caylee:
#1 Take pics with cell phone
#2 Go straight to kid and say "gosh you sure are a cutie! You look just like my little girl's friend Caylee. Is your name Caylee? Is your grandpa Jojo?"
Kid will nod or say yes - they can't help it at that age no matter what they have been told!
#3 I look around very fast to see the reaction of people around me. Any running away? Any watching intently and acting nervous?
#4 A "real" parent would be alarmed at anyone they don't know speaking to their child and would be already headed my way. I explain and apologize when and if I am absolutely sure this isn't her...."real" parent will totally understand!!!
#5 If I get any indication that it is her, I dial 911 right now and do not leave the child for one second. While waiting for 911 to respond I grab the nearest person's arm with urgency and say "I think this is Caylee Anthony the missing little girl!! Hurry! Go get Mall Security - PLEASE!!!! Get me any store manager!!! PLEASE! Leave your husband here to help me watch her....
I do NOT:
#1 Take pics and continue walking!!!! DUHHHHH! WTF moment here!
