The question is: what do you do? Whether it’s a legitimate government force, a rogue force previously under government control, or outright imposters, does it make a difference? How would you react to the use of force or implied threat of force to sieze your property?
I think its important to understand the overall situation and draw a line for yourself. At some point everyone who wants something becomes an enemy. The question is when and that is so dependent on many local factors that just common sense and good judgement can help to answer this.
It might sound weird but the benefit of living in a country with corrupt police and military forces is that you know that you can draw the line pretty early on in the game. Where I live, even in normal times, the police and military run the show. We do not have mafia or organized crime because police and military take care of that.
