Part of the problem is the time it takes to get things before any court. In this covid situation governors know that it takes way more than 120 days to get a case before any court. So by that time all these cases become moot because they will remove the restrictions thus opening society in their state. So they get away with it. Even if they charge and fine someone they will vacate those actions before the supreme court can make a ruling . So the next time this same thing will happen again. The second go round may well trigger more forceful resistance as it should.
The courts in this country are irretrievably broken. You might be interested in this post that traces a case from the initial charges to the supreme court in 1938, then compare it to any case today.
The concept of "swift justice" is laughable today.
