Thanks for taking the time to answer in detail. I guess i agree with most of what you wrote but some of those points rely on the fact that jedi can predict things in advance or not. So that ability seems to be (to me) still a speculation.
Regarding "Detection/Hiding their minds", i recall lord Scorge doing so in the Revan novel when Then again, the novel has a few negative views so does that make it an invalid example? If not then it is possible for jedi/sith, but i have no idea if a non force user can (which is the main subject here i guess).
If non force users can then they should be able to snipe (for example) a jedi/sith without it even knowing that there were any danger.
Anyway, basically : I don't actually believe jedi/sith can predict bad things happening in the near futur, hence making them vulnerable to mines and long distance snipers. They could prepare for an attack from a distant sniper and block the attack eventually with its saber, since they have good reflexes but then again it comes down to whether or not a non force user can hide their presence (or at least train in that particular section since all beings seem to have the force in them).
I can't believe i spent about 30 minutes writing this...didn't think it would take that long to get my thoughts (or a rough idea of it anyway haha) on "paper".
