US military can temporarily detain protesters in Los Angeles, commander says

Here’s the relevant section of the article that the title is referencing:

He emphasized that while troops can temporarily detain individuals, they must wait for law enforcement officers to make actual arrests.

Unless the guard troops are working directly with law enforcement, or are there at the request of the state, or the Insurrection Act has been invoked, none of which have happened or are the case, then it is completely illegal for them to be detaining anyone for any reason. Those troops should be refusing to follow those illegal orders. As should their commanding officer, but I’m getting the impression this is not a guy with a lot of critical thinking skills.
