Why does mr.walker say that India is free while reporting on the demonstration at the dharasana salt?

Mr. Walker asserts that India is free during his report on the demonstration at the Dharasana salt works to highlight the irony of the situation. Despite India gaining independence from British rule, the ongoing oppression and violent response to peaceful protests reveal that true freedom is still unattained for many citizens. His statement emphasizes the contrast between the formal declaration of freedom and the reality of continued struggle for rights and justice.
