The supposed anti-terror acts always have and always will be an attack on our constitution. The Bush Patriot Act undermined personal freedom and the Biden attempt is no different.
I agree..not that the examples you quoted are the only times our govt. has gone rogue on the people. From the Civil war to the cold war...and hence to the war on terror--The govt. always says it needs the tools to protect us..and it is always us that the tools end up being used against.
We have more than enough laws in place now..we just have to use them..if we wish to. We do not need a tightening of the screws...quite the opposite..IMO.
That being said...those who actually act on their revolutionary rhetoric----with violence----get the mad dog treatment.
