They handed over 200 documents plus financial records.

Without knowing what was specifically submitted, the quantity doesn’t say much.

I could provide hundreds of pages of spam emails, automated messages from my bank and every online store I’ve bought stuff from, and still leave out any communication which was specifically requested by the court.

Example:

You use Firefox, you occasionally use IE to download MS updates and when you accidentally click on a link generated by windows.

You use Firefox to Google “how to commit murder” and “how to remove blood from fabric” and then are accused of committing a murder around that same time.

You get a subpoena for your electronic communications and searches.

You only submit your IE searches (and delete your Firefox History).

You are in contempt. The prosecutor would have the expert note that you use the computer for X hours a day (as per the logs that build up as you are online), yet IE shows minimal usage.

Your Firefox shows no history, however there is a bookmark in your browser from after the time you received the subpoena. Therefore, you cleared your browser history after you were subpoenaed.

You have Firefox installed (which you would have to go out of your way to do), but submitted no Firefox logs or empty logs.

These logs also show logged activity from Firefox during the period of missing browser history.
