1. There is no evidence jefferson ever said this

2. There is no evidence anyone else ever said this, either

The closest you get is MLK.

See https://www.monticello.org/research-education/thomas-jeffers...

But MLK also talks about moral obligation and not other forms of obligation.

He was not trying to create a free for all where everyone gets to decide which laws are okay or not, because he (and jefferson) were not complete morons.

Is it unjust to prohibit the sale of illegal drugs, weapons, etc.? Society has good reasons for regulating certain goods. I regularly see people in my community who are enslaved by fentanyl and I wouldn’t wish it on my worst enemy. The society I live in decided to make selling it illegal. What is unjust about that?

so we all individually can just decide a law is unjust? that'll be fun

Maybe Thoreau? That's more authentic and gets at similar themes. On more than one level considering his circumstances and run-ins with law enforcement.

”Under a government which imprisons any unjustly, the true place for a just man is also a prison."

I wonder how this sentiment is going to play out in Luigi Mangione's trial.

Thomas Jefferson was a slave owner.

He tried to have multiple people murdered.
