Was, as in, is no longer? If that's the case, she's probably fine. Jake hasn't gotten to the extent of murder or anything, but, he did some criminal activities right before he was taken, too. In fact, he was in prison when he was brought here to the Port.

While he does make it a point to uphold the law, technically, if she's not doing anything like that in the Port it's not against the law anymore. :) So! That should still give you ample opportunity to learn about your little one's past while still keeping Jake's sanity in check.
