Does anyone know if it's legal to protest at a Presidential inauguration? I know there's no specific law against it, but will the police/Secret Service arrest you if you hold up a placard saying "Biden swindled the election," that he's not the legitimate president?
The DC police will setup ridiculous rules shunting any protest as far from the inauguration as possible. They will use COVID regulations as an excuse, and will suppress any deviation from said rules with far more ruthlessness than they did against the protesters at Trump's inauguration.
This will be despite the far more passive mindset that will be shown by the right wing protesters.
