The issue isn’t whether sending troops to LA was necessary (it wasn’t), whether the demonstrations had turned into something like riots (they had), or whether the troops were accomplishing anything useful (they weren’t). No, the question now is how far Trump is prepared to press the issue. Is this the point where troops are sent all over the country to shoot peaceful protesters? Will Trump attempt to replace the governments of blue states? TBD.
I predicted last year that public protests against immigration policy would provide the equivalent of the Reichstag Fire if Trump had the audacity to use it. Nothing in the last few days has caused me to change my mind, although it has not happened yet.
