I don't even let my 11 yr old stay home alone let alone be in a public place alone. I'm just too paranoid. Things aren't like they were when I was a kid (as I shiver because I sound like my mother! haha!)
No. Ever seen how teenagers act when together at the mall. They seem to 'forget' their manners...even the usually well behaved ones.
I have a hard time understanding how 'they'll have a cell phone' and 'we meet up every so often' makes you feel your kids will be 'safe'. What if the cell is taken away by someone? What if they don't meet you at the designated place or time? Then what do you do?
Most of us longtime Disers have read stories on here of teenagers (around 16yr) from a certain country who visit WDW as a tour group, and how they act...and how their parents back home would be mortified if they knew!
Maybe you were one of the sheep at the mall.
Why the personal attack? I thought this was a friendly thread? The OP asked for opinions, I would think that every one she gets will not be exactly the same -- since people do have different experiences, they will share those. The OP gets to decide what is valid for her and what should be ignored, but everyone should be able to share without needing a fire retardant keyboard. 
How are they different? Other than news coverage?
I have to say, if I were walking by and saw a lone 2 y/o in Epcot kicking the dirt, I would absolutely stop and talk to him. If no one was coming for him, it wouldn't be very long before I took him by the hand to guest services for Lost Children. It's very likely that couple was distressed to see a little boy all alone in a big park like Epcot, and it was very innocuous. Maybe they wanted to avoid a potential confrontation with his caregiver?
Heck, I've been known to turn my car around if I see a preschooler walking on the sidewalk with no adult in sight. Really. And strays too...![]()

I bet you are going to get a bunch of different answers.
For me...NO WAY.
