Do you understand the concept of 'emergency circumstances'? And "temporary restrictions"?
There have been a LOT of emergency situations over the history of our country.
There have been a lot of 'emergency orders' that were put in place. Many (most?) of those orders violated constitutional rights in some way.
Many were taken to court. While some were found to be illegal, most (by far) were found to be legal. Even some that were patently wrong (internment of US citizens of Japanese descent during WW2 for example).
Right now, most states have emergency orders in place that infringe on the right to 'peaceably assemble'. There have been reports of police enforcing those orders and, local to me, a few tickets have been written. Mostly warnings, but some fools have decided to 'stand up for their rights'.
Admirable behavior under normal circumstances, but right now it is stupid and dangerous. Not just to the individual, but to the community as a whole.
I have no doubt that some of those who were cited will choose to fight it. I wouldn't bet on them winning.
