Bullet-proof public toilet

That’s right, a bullet-proof outhouse. You know, for those scenarios when you’re in a public venue with nowhere to hide during a terrorist attack. The safest place to seek shelter and protection for citizens in Beijing’s Zhongguan Village square can find both in the nearest “outhouse”.
Costing about US$100,000, this special toilet’s exterior remains intact even if ordinary TNT is detonated within.
That’s one costly unit. If the structure can withstand a TNT detonation from within, the outside should be impervious correct?

“intact even if ordinary TNT is detonated within”
Forget Beijing. This is ready for some good American chili……
