Has anyone witnessed any act of kidnapping as seen and heard on TV?

No, I haven't ever witnessed any such act on TV, but yes, read every now and then about such incidents in the newspaper. Such incidents have increased in number and they do not make for eyeball grabbing news anymore for the news channels to report, as then perhaps the entire news will be about kidnapping and stuff. Sad!

No, I haven't. And I don't know what I'll do if that happens. I might be too shock to help/respond.
