@Treyon, I highly doubt that's going to work. People of the planet might be ignorant but not stupid. The more you supress people, the stronger they retaliate. High tech supression might work at first but it'll be fragile and won't last 1200 years before it splits into smaller countries fighting...
@Treyon, not that easy. You can silence people who revolt but if you start big, it's easy to infiltrate and scheme long-term and corrupt your empire from the inside. Great things always start simple. A small but strong country is a good start.
Why is this going this route? Hopefully, this is just for this one case. He might as well have returned as a cop instead of a prosecutor if he'd be doing these kinds of job. It would have been better if he befriended a passionate cop who would do this for him so he could focus in court.
