Does the US legal system still exist in any sense that it should in a democracy?

I ask because I don’t understand how all this is possible in a constitutional state: Masked brutes who arbitrarily kidnap people on the open street without even identifying themselves, people who are interned without due process and then often simply disappear without a trace in the administrative system, total surveillance without cause, and many other massive violations that the US legal system seems to enable rather than prevent, as it should.

All of this already looks very much like a dictatorship to me, i.e., an unjust state, as none of this can be possible with a democratic constitution - at least not with one that is actually upheld by the legal system.

No.

The people are so gaslit they will attack you if you say otherwise.

I wonder why our allies aren’t helping at this point. Surely they understand where this goes if they don’t stop it sooner rather than later. Europe is laughing at Americans ignoring the tiger that will eat them soon.
