In this situation, people are ignoring the kid, but still watch in shock. And as weapon, you can picture a very dangerous and clearly sharp knife.

But like I said to the other responder, if you hurt the kid, people might see you as the bad guy, because they all think that anyone that hurts a kid, even when that kid is clearly the bad guy, is a bad person.

I should have put on there, that everybody is seeing the incident but are too scared to be labeled as someone who hurts kids.
