One of the bigger problems was all the manure on the streets. I believe this is one of the reasons why there are stoops in New York, the steps up to brown stones.

Also there’s a dump site in New York called Dead Horse bay.

Now doubt there’s many people here who have been to New York, I’ve just seen YouTube videos about this.

Stoops in London? I’m guessing quite a few properties have steps up to the entrance. Going through YouTube videos of shooting locations of the Sweeney and it doesn’t seem that prevalent.
