While I agree with Gorsuch's general view on vague laws, I don't understand his reference to "salesmen peddling shady" or whatever products.
All the definitions I looked up for burglary included "uninvited presence in a building to commit a crime".
How is standing outside a door talking to the resident considered burglary?
"Entering a store, shop, office building, or other structure used for business purposes with the intent to steal something, or to commit another type of felony, is considered “commercial burglary."
Gorsuch should have been more concise in his "door-to-door salesmen peddling shady products" phrase. Salesmen go into public places of business every day to present their products. If shady (maybe his term for fraudulent) then it would be considered burglary under California law.
Still, he should have used the phrase, "commercial burglary" because "residential burglary" is uninvited entrance with intent to commit a crime.
But then, Hillary had no INTENT when she set up her private server and used it to store classified documents. Again, the word INTENT. John Schmo, while being distracted, had no INTENT when he mowed down the civilians on the sidewalk and charged with man-slaughter.
