Sn Brussels Airlines truly took a hands on approach to warning its travelers about pickpockets (sorry, that was bad). These freakish plastic hands were slipped into unattended or unprotected backpacks, purses and luggage. On an individual level, I am sure feeling personally violated will help you keep your guard up in the future. But really, how many hands can you slip into people's bags in a day. Interesting idea, but it seems like a lot of effort to freak a handful of people out.
