Silence is silence.
If enough people get the complete thug treatment (not allowed to call their lawyer, beaten, shot out of hand, etc.), word will get out. The thugs and their bosses are human and WILL make mistakes - and on average they aren’t all that bright. Besides, somewhere along the line one or several of them will turn in their comrades fir one of several reasons - thus kind of thing cannot be kept quiet. Then there will be a reaction.
Not everything is as bleak as you think. The enemy is not all powerful or all knowing.
To clarify. The thrust if my point is that we are greatly underestimating the enemy. This is a recipe for failure.
The belief that confiscation cannot be hidden from the public is utterly false and a dangerous mindset. It is already happening and has been for a long time. Take any city or town of any significant size and you will find local Police SWAT teams conduct dozens, even hundreds of raids every month and you will hear about one or two on the local news. The dozens of others you will hear nothing about and have no way of finding out any information or detail about such raids. Red flag laws have been on the books in several states for some time including FL and they have been used extensively to take guns from law abiding citizens. Red flag law enforcement is being used on a large scale yet the public is being kept in the dark. Gun confiscation raids will be kept even tighter for obvious reasons. Ask yourself, if you have no means to find out about dozens of raids your local police departments are conducting how do you think you will find out about confiscation raids?
