That is the obvious conclusion, but you have to be suspicious when things look too obvious. It is possible that this woman had some personal enemies who wanted to cause her ill (like a jilted ex-boyfriend). The authorities would be negligent if they rules that possibility out.
Possibly, but in my opinion, not probable.
I believe it is more a muslim sow pig wanting to throw acid in the face of an infidel who is selling something they consider to be against their ‘religion’.
I foresee many more of these attacks with these sow whores using their ‘religious’ garb as a way to prevent identification.
