Make sure you won't come across scumbag players, who, even if you paid every fine, will FR5 you - so make military and police rephacked from house these players belong to, so you can't repair it even with bribes on stations.
It's a very OP move, which is harmful for roleplay and activity. One faction was indirectly threatened with that (even though they paid every fine they were given), so they moved from that place.
