I guess I feel the opposite because I'm only 22? Maybe my opinion will change whenever I have kids but I feel like if my mom would have done that to me I would have just stashed my cell phone somewhere and left anyways. I got a cell phone when I got my license because my dad wanted me to be able to call for help in emergencies.
I guess, I know I did a lot of stupid stuff when I was a teenager but if you look at the stats, most abuse/kidnappings/rape happen between people that already know each other. Most kids are not in danger of being snatched up by a random person. It's something like 80% of girls who are raped are raped by someone they know so I just don't see complete strangers as a threat. And I grew up in Dayton and Cincinnati. I guess I just feel like it would make more sense to have your child take a self defense class than track their phone? I took one and am quite confident that if someone tried to attack me I could fend them off to at least get away. My dad has always been very pro-freedom and rather just teach me how to defend myself so I guess I don't see the point.
Good points from everyone though. It's always interesting for me to see the complete opposite side of my thoughts.
