Liquor rather than gold?

A year ago I found out that Seymour was involved in the illegal trade of liquor with the "Indians" and that he was sentenced for that to six month hard labour in 1882. Click here for that story.
I suspected something similar about Bee, who was known to police in New Westminster. He was indeed in the same business as his friend Seymour. Following from The Daily Colonist of 10 June 1887--

Louis Bee, a half breed, was arrested some days ago for supplying liquor to Indians, and was this morning sentenced by the police magistrate to six months imprisonment with hard labour.

And these two rehabilitated convicts were camping right in the middle of Pitt Meadows with no other purpose than fishing sturgeon. Do you believe that?
