There are charges laid against Meng in public, the whole world can see what she's accused of. So far, there seems to be rule of law.

The Canadians in China have vanished: we don't know why they if they have been arrested, charged, there's no hint of anything.

So yes - 'being charged in a court of law' is rather different from 'government agents arbitrarily grabbing you off the street'.

Once again doesn't answer the original question. How did the commenter come to the conclusion that two people were randomly arrested?

We still don't know why they have been arrested. The only reason that China has given was they were 'endangering national security'. Seeing that they use this reason every time they want to arrest a dissident, it seems like a random arrest.
