American citizens being shot and brutalized by a state sponsored force of masked thugs without training. Sounds pretty clandestine to me and it's happening in us soil.

Except those actions are not secret, nor illegal, nor a threat to any other country’s sovereignty?

If you think those actions are not illegal I'm stopping to reply, this is clearly just ragebait.

Ragebait would be trying to argue that China running secret police and propaganda operations on Canadian soil, against Canadian citizens, is in any way equivalent to a domestic force taking actions primarily against foreign nationals, in a statutorily authorized way within a legal framework that can be challenged.

TIL enforcing laws is actually illegal

There are many cases of law enforcement being imprisoned for shooting people while on duty. It is well established that enforcing laws does not give you carte blanche to shoot people

Their actions are very illegal (extradition if American citizens, stealing property, entering without a warrant, murders, etc.).

And the US's stance and actions around Venezuela and Greenland are also both illegal and a threat to a country's sovereignty.

Tariff threats is another example.
