What is it with you and the mall kidnapping? Do you know that only only a tiny percentage of child kidknapping's are done by strangers?
Most are children involved in custody battles.
In most serious crimes (rape, kidnapping, murder), the victim and perpetrator know each other - or are at least "acquainted". "Random attacks" statistically pale in comparison, and in those cases a better sense of "awareness" (which is learned in Aikido, or any other martial art) could help cut down the number of those incidents.
