@Setanta,
By the way, the more important thing here is not Gunga Dim's false analogy, it's that he offered in the vein of a stupid, cynical and callous crowing over the death of a young, who he does not know for a fact had assaulted Zimmerman. The only evidence we have that Martin assaulted Zimmerman is Zimmerman's claim to that effect--and given that he's facing a second degree murder charge, and very likely knew from the beginning that he might be charged with a crime, it's reasonable to consider him an untrustworthy witness.
Gunga has made this cynical and callous remark, this stupid remark, in my opinion because he is a typical sociopathic conservative who doesn't care that Matrin was killed, he just excited by a case of some clown using lethal force.
