"tangible goods" may be necessarily broad to limit actual criminals' ability to do an end-run around whatever limits S-O sets. Likewise for RICO, PATRIOT Act, etc. The problem isn't in how you use them to *catch* criminals, the problem is how you can destroy someone's life for committing a petty crime, or worse, punish an innocent because the law is so powerful that the accused can't properly mount a defense or cops a plea to avoid even larger sentence.
Should the captain and/or crew go to jail? Probably; destruction of evidence needs to carry a serious punishment. Is 20 years an appropriate punishment? Certainly not compared to the crimes the 20-yr option was intended to prosecute.
If these laws are necessarily broad, then they need limitations as to when the full weight of punishment is appropriate.
