If you’ve ever been to a bank or a convenience store in Japan, you might have noticed, tucked away behind the counter but still easily accessible (to the staff, that is), some orange balls. If you look more carefully, you’ll see that they’re actually clear balls filled with some sort of orange liquid. Any idea what they might be?

Well, let me tell you. They’re actually to protect against crimes. They’re called ‘bohan colour balls’ (crime prevention colour balls), but I prefer the alternative (and far more attention-grabbing) ‘crackball’. Whatever the name, the idea is that staff can throw the balls at any criminals who are trying to escape.

Good idea, but it raises one question (actually, several): do the staff actually practice throwing these balls? How do they learn to aim? What if they hit a completely innocent bystander? The whole ‘orange ball’ system just seems very prone to mistakes, let’s put it that way.

I certainly wouldn’t have any confidence that I would be able to hit anyone who’d just stolen something from my shop or, worse still, from my bank… but maybe that’s just me.

Footnote: It appears that people possibly do practice throwing the balls. There’s even a website (unfortunately only in Japanese, but then again, why would it be in any other language?) explaining everything you could ever want to know (and quite possibly more) about how to use the balls.
