The police are more focused on dealing with internal criminals. Go complain at them.
Edit: Let me explain that comment in a little more detail.
Sure, the military does deal with internal security issues. The problem is every last military in sirius is at war with another house. This means that during those factions are online, they will want to be doing that element of the job. Like Alec said, people have limited time, and we play this game for the kicks, not to chase around after miners who can't be bothered to hire their own security.
Fighting the various wars is much more fulfilling in terms of military RP, and the fun times to be had. Police RP is much much more focused on dealing with issues such as this. Protecting trade from internal criminal elements and so on. Security at mining sites should be provided more by the police and the company's own security wing alongside mercs and bounty hunters.
The [LN] often gets stuck in the following situation.
- We get complained at for not actively persecuting the war with rheinland.
- We head off into rheinland and I get PM'd by 29386492649827648726424 traders who're pissed off about the nineteen pirates in california.
