Funny, but sometimes you do want to clean up your laptop - for example, before crossing the US border.

I would be irked if I had taken steps to remove a downloaded file from my laptop, including secure deletion, only to leave evidence that I'd downloaded it in a sqlite database.

If you are worried about that kind of thing, I'd recommend doing that stuff in a VM with an encrypted file system. Then, when you delete it, you know everything is gone.
