>What dissenting voices are being imprisoned?

There have been a lot of political prosecutions of people who disagree. James Comey, Leticia James, John Bolton, Mark Kelly. Luckily, grand juries and judges have prevented them from getting convictions. But dragging them through the legal process is punishment enough. The administration's incompetence at imprisoning political opponents isn't a reason to forgive them.

ICE has targeted protestors, and Rubio made it clear the targeting was intentional policy.

If we look beyond "imprisonment" and include "illegally or unfairly punish dissenting voices to keep them from having a voice," there are a lot more victims. Jimmy Kimmel, reporters at the Pentagon, openly supporting an ally's takeover of Warner Brothers to control CNN.
