Well, have a look at this photo, especially what the grabber is doing with his hands - it's very plausible and highly likely that there were scratches.
 I use "grabber" guardedly, since a person who by force of arms takes and carries away is a robber, at least here under the common law, so a more accurate description would be "attempted robber".
 As for your argument about idiocy... that's like saying rape victims are at fault by wearing skimpy dresses. What's wrong is wrong is wrong - and using violence against an innocent civilian to promote a political agenda is wrong, and you cannot justify it by the (tenuously connected) actions of another.
