No, you weren't. You asked:

"Can you cite any examples of *this* happening? I’m a pretty big policing reform person and follow this stuff closely and can’t think of a single case *like this*." [Emphasis added]

The semantics of that question turn entirely on the antecedent of "this", which is pretty ambiguous in this (!) context.

So I'll revise my criticism of your original remark: you need to be clearer about the scope of what you are asking about. Personally, I don't think it is at all unreasonable to extrapolate the circumstances of the GF case to the potential for the same thing to happen during a border search, but I suppose reasonable people could disagree.
