Foxfyre opened her Rebellion thread with a disclaimer clearly outlining her OP's hypothetical nature, to, I'm assuming, potentially counter or dissuade a reader with judicial or federal authority launching proceedings against a percieved threat contained within the OP. Would you take similar precautions should you submit a similar or identical OP for public scrutiny, considering state agents may take an interest? It's common knowledge they search and filter the web looking for leads.
Personally, I doubt anything I've written on here qualifies as a threat. Nor do I believe any of my online activities have been cause for concern among the security services.
