Imagine it's 1909 in Brooklyn, New York around 9 a.m.

You're walking along through an Italian neighborhood,

munching on an apple for breakfast.

Suddenly, you hear something.

It's coming from the next block over.

You look up, and above the roof line you can already see smoke,

thick brown clouds.

You start running, but you know immediately where it's coming from.

People have been calling that factory a death trap for years.

You rush off and, sure enough, the factories engulfed in flames,

from basement to roof.

You see a young black man hauling a limp burned body out the door.

Then above you, more screams.

You look up and see people at the windows on the third floor.

You yell at them to jump, jump!

Then you realize that they're trapped behind iron bars.

In fact, every window at the factory has bars to keep burglars out.

But right now, those safety bars have trapped people inside.

They're facing death, and they know it.

They're screaming and shaking the bars like rabid apes in a cage.

Luckily, people start arriving with ladders from another nearby factory.

Another person rushes up with sledgehammers.
