I would definitely mention this in a short email to your bosses direct supervisor, or if you don't trust him, as far up the chain as you would like to go, if this involves violating law, you obviously need to not violate that. However, the chances that they will side with you are low, so remain very civil, and be ok if that happens. There is a chance they won't terminate your boss - and will try to get you to "patch things over", which probably won't work. Still, you're nicely on the record for having reported it. If they don't respect you for nicely reporting it, it sounds like you don't want to be there anyway. While it may be unwise to say "don't get a lawyer", I don't think you want to win that fight, as then they really will not want to have you aboard. I'd also consider the matter of the compliance document - if this is just something like import/export compliance, it's really not that hard, and your boss may have been reacting to the tone in which it was brought up, rather than what you brought up. Sounds like it's a bit more than that though. Companies are very likely to lay people off these days, especially so they can get them to sign agreements that limit their ability to converse on topics (i.e. severance or at least mutual non-dispargement agreements, waiving ability to sue, etc). They are unlikely to actually fire you, and if they do, I'd just be very up front about what happened when talking to companies you are interviewing with. They are likely to understand. It's all in your emotions and how you talk about it. Having good positive references at that company is of course a good thing to have as well. Do be looking for a job now though.
