    The Red, the Black, and the Green

    After Minneapolis police officer Derek Chauvin murdered George Floyd last year, tens of thousands of people all over the world took to the streets to protest police violence against Black people. And if you look at images from these marches, you will probably start to notice a common color scheme -- one involving a lot of red, black, and green. The flag was invented to unite Black people all over the world living under racial repression. When it first came into existence, the flag posed some bold questions about where Black people owed their loyalty: was it to the nations where their lives were demeaned and threatened? Or to a new nation - one they would build entirely for themselves? For hundreds of thousands of Black people, the red-black-and-green symbolized the answer.

    The Return of Con Law

    We heard you. The chorus of voices asking “where is Con Law? Where is Professor Elizabeth Joh to guide us through this madness? We need it now more than ever!” Well, here it is. We’re back with a special extra-long episode about Trump’s perverted use of the Alien Enemies Act to deport people without due process and how judges are trying to hold the administration accountable to the Constitution.

    Plus, we announce the launch of The 99% Invisible Breakdown: The Constitution, where Elizabeth and Roman will tackle a different section of this 7600-word document each month, treating the Constitution as a text to be analyzed.

    😅⚖️

    A single 👍 emoji sent over text was meant to say “got it”—but instead, it kicked off a $62,000 legal battle and raised the question: can an emoji seal a contract?

    Changing Stripes Revisited

    At the January 6th Capitol insurrection, rioters waved Confederate, MAGA, and Trump-as-Rambo flags. Easy to miss without knowing the design was a bright yellow flag with three red stripes — the flag of South Vietnam.

    There were actually several confounding international flags present at the Capitol riot that day: the Canadian, Indian, South Korean flags, all were spotted somewhere in the mayhem. But what was peculiar about the Vietnamese flag being there was that it's not technically the flag of Vietnam but the Republic of Vietnam, a country that no longer exists. And what this flag stands for (or should stand for) remains a really contentious issue for the Vietnamese American community.

    This episode originally aired in 2021.
