I have a jury summons for tomorrow, and I'm scared

I have a jury summons for tomorrow [to be in a jury pool, not to appear before a gorram grand jury], and I'm scared. I could be jailed for refusing to do wrong. I also have ptsd. I ought to be more afraid of missing an opportunity to help someone in danger than afraid of being jailed or being bashed again. Inaction in the face of violence is also violence but participation in a system of injustice tends to reinforce the injustice.

One of my older posts on justice may be relevant here:

What is justice? I would define it as righting wrongs.

Helping the victims. Helping people heal. Helping people avoid having to face the same wrongs again. And one of the wrongs is that our institutions are based on domination, our culture is based on silencing, and many people's instinct for justice and compassion has been turned into another tool for domination, and with it, for injustice and brutality.

Punishment/retribution/revenge is not justice.
