“Israel won’t pay medical bill for wounded American” has no negative bias about Israel except for its headline.
Now, a headline is what most people read, so it’s not a trivial thing!
Doesn’t it sound unfriendly? Doesn’t it remind us of all the bad things that Israel is accused of all the time?
Why not: “American-Israeli not automatically entitled to medical costs in demonstration injury”?
This will be fought over in court, so the qualifier “automatically” just means: for the time being.
So, a serious AP bias, after all.
