on your first point, I wonder: are the Greek authorities worried about the strain (I actually first typed "stain"!) on the ability of the police to effectively fight real crime while hundreds or thousands of its force are dedicated to the violent assault of peaceful protesters?   Yes, I agree that it would be a shame if a person lost life or property because a hijacked fire truck was being used to douse the CS tear gas used 'wrongly, needlessly and brutally) against protesters.  But do we blame the protesters for that or the police?  If I'm violently assaulted and I defend myself using the only means at my disposal, and, in the process, a third-party is inadvertently injured, am I rightly blameable for this or is it rather the responsibility of the person(s) who assaulted me?

   Why don't the police and the government abusing their authority have to suffer from very, very bad press?

on your second point,

   "And dressing up like medical personnel is a war crime for a reason."

    There's a reason--or there used to be one--why wars are formally declared by governments: the laws of war then apply to the parties concerned.  In this case, the only war going on is the one being waged by the Greek government against its "own" people, the Greeks.  I don't recall that they declared that war either.  Instead, they simply started beating and shooting at people.

   Now, it may also be a criminal offense in common law to wear hospital garb --surgeon's apparel though I tend to think that what the law really says is that no one may falsely impersonate a medical doctor.  I don't see why that necessarily precludes wearing surgeon's scrubs to a street protest.  If asked, the protesters could say, "I'm not actually a surgeon, I just dress like one for street protests."  As George Costanza would say, "Is that wrong?"  And, as I would say, "Is it wrong-er than most of what the police and official government show no scrupple to abstain from doing?

   I recognize that telling lies is wrong, and so is stealing.  So, when the next Nazi-like regime tells you it's your responsibility under the law to report all those who fall into the category of being "X", do you dutifully report them or do you lie and do your utmost to protect them and at the same time your utmost to frustrate and defeat the objectives of the Nazi-like authorities?

   Everything the French (and other) resistance movements did against the Nazis in WWII was a crime, often punishable by death.  People deliberately broke those laws and they were both right and courageous to do so.

   Sometimes dressing up like a surgeon pales in terms of its terpitude when viewed in the context of the circumstances which may prompt one to do that.

   Brutal, law-breaking authorities hardly deserve the strict to-the-letter obedience of the public they are criminally and violently brutalizing.  When this undeclared war is over, I certainly hope some people face criminal charges for their actions.  ALmost all of them are in positions of authority.
