It looks like the author at RRW didn't read the article well.
Rascatripas was not hung from the infamous overpass. His body was dumped in town at the base of a statue where other bodies have been dumped in the past.
The past tense of "to hang" when referring to a human being (as in "by the neck until dead") is "hanged" - i.e. "Rascatripas was not hanged from the infamous overpass."
No it's not, or more correctly, that is a rather recent development. The Middle English account of a man punished given on Wikipedia uses hung (http://en.wikipedia.org/wiki/Hanged,_drawn_and_quartered), in fact this punishment was referred to as "hung, drawn, and quartered".
Now, if that is the case, how to explain the title of the Wikipedia entry, i.e. the usage of hanged in place of hung. This is the common phenomenon of regularization of irregular verbs, that has been going a loong time in English, eventually almost all of them will be regularized. This article (http://www.dailymail.co.uk/news/article-486935/How-irregular...) gives some details and explains that there are about 98 irregular verbs left in the language, compared to 177 in Old English.
You can see this process today in the "driven-drove" dichotomy, different people choose one or the other. Eventually drove will disappear.
It's a little more subtle than that. There are usage differences between the perfect and imperfect tenses in both "hung-hanged" and "driven-drove," between active and passive constructions[1], etc. Unfortunately, most native speakers aren't any more savvy to this than they are to what remains of the English subjunctive.
1. It will always be "I drove to the store" and "I was driven to the store" and "I am a driven person," never "I driven to the store" or "I was drove to the store" or "I am a drove person."
Not only that, but neither "driven" nor "drove" is a regular past-tense form. That would be "drived", a use I haven't heard from anyone over two years of age.
Yes and no. Some people call ablaut verbs irregular, but almost all of them are in fact regular. They only seem irregular because there are relatively few of them left to group together [1]. But I'm not aware of any language with a single pattern of conjugation. Many have 10 or more.
1. Ex.: Drive-drove-driven, write-wrote-written, ride-rode-ridden, etc. While they follow a different conjugation pattern, most ablaut verbs are perfectly regular.
I hate to go off-topic again on such a sensitive subject - but am I the only one that finds a discussion on grammar quite distasteful when we're talking about somebody's death? There's a time and a place for that kind of discussion, and this is neither the time nor the place.
