I agree with the consensus here. In my discussions with ILF and others, if you even get a inkling of actual content, DO NOT capture or do anything with it. Stop immediately, notify your contacts if in corporate environment and ensure they report to LE. I would advise you also contact your local counsel and ensure you disclose to them what is required.
In essence, like they said - stop, drop and roll. Do not tamper, copy, record or do anything with actual content otherwise you will also likely face some criminal charges yourself. As crazy as this sounds, ensure you have a direct line to your local field office or via Infraguard - you will be provided with the means to communicate that should that situation ever arise.
In this profession, hope for the best - plan for the worst.
