This was a big deal after the Camp and Complex fires because of some viral articles that drew well justified outrage among Californians so they went a step above and just allowed them to expunge their records completely (so that they can get hired everywhere else too, they don’t have to become fire fighters).
There are some stipulations like the sentence they served must be at most 8 years, but they’re not all banned from continuing their work.

I'm honestly surprised at the downvotes. I thought this was common knowledge.
That seems really really low!
Also, arson convictions are extremely rare. Most arsons are unsolved.
You can imagine how much more likely it is to be unsolved if the person investigating is also setting the fires
