It's former Ammatar soldiers and policemen...
Any violence because they're Ammatar will be seen as being because they're religious and/or Starkmanir.
Thereby deepening the divisions.
So.. what's the Brutor Tribe's angle on this? Going to exploit the inevitable violence and claim the Starkmanir can't govern themselves and so do not deserve membership of the Tribal Council?
Well, a couple things. One, the Stankmanir and the Brutor are closely related, the Brutor are in fact a Starkmanir offshoot. So it could be seen as trying to help kin.
And, well, the Brutor Tribe could simply be trying to honestly keep order, thus helping Shakur's reign.
Its been noted before that giving up on a kinsman, regardless of what they've done, is rather against the Minmatar mindset. (see, The Burning Life where they basically use those words, Valklear, etc)
The Matari seem to value blood over quite a bit. So, from a Brutor standpoint, standing by and letting their kin be killed, even if theyre spouting Amarrian nonsense, might be seen as un-Matari.
