Looks like a regular charter bus here, too. I'm not sure if there's a regulation about the hammers here. Could be. And maybe none of them ever noticed them or knew what they were. Pretty conspicuous: bright red, hammer-shaped, molded grip with a handguard, ground steel point; I just took it for granted people knew what they were. I think there's usually a decal in the corner with a pictogram showing where you should hit it. It's been a while since I was on a bus

Edit: correcting the autocorrect

I was wondering just how important the detail that it's school issued is—like, would she have done it if it were her own?

Yeah, but every bus I've been on in Germany has had red window breaking hammer clipped above the windows. I wonder why none of the students ever noticed them
