I'm dealing with a recent tornado issue in my neighborhood in the US. Thank god for those immigrants!
I was amazed at how fast they were in removing trees from the tops of houses, blocking driveways and side-streets, and other essential places. Large tree removal in urban areas is difficult and potentially dangerous. Yes, they were paid (very well I hope) but they were very good in quickly and safely removing large trees and debris from places where people were trying to salvage their homes and get on with life.
I don't know if any or all of them were illegal and I don't care. This neighborhood, where my very elderly Mom also lives, would be in chaos without the work they'd done.
