King issues the Letter from Birmingham Jail as a public brief against delay
On 16 April 1963 King dated the Letter from Birmingham Jail, defending direct action against ‘wait,’ distinguishing just and unjust law, and answering white moderate clergy. In the causal graph this event strengthens Judicial independence erosion (court capture), a driver that strengthens Rule of Law Gap from the Highest Governance Score — a worsening welfare path.

On 16 April 1963 King dated the Letter from Birmingham Jail, defending direct action against ‘wait,’ distinguishing just and unjust law, and answering white moderate clergy.
Context
A jail letter is not a court. Analogical justice path: it is a public brief that unjust statute does not bind conscience and that delay is itself a holding.
Martin Luther King Jr.’s documented role is bounded by other offices and collaborators named in the sources below.
Written on smuggled paper after the Good Friday arrest. Addressed to white clergymen who had called the protests untimely. Later published widely.
Why it matters
A letter is not the children’s march. Split May.
