The Urban Dictionary gives a fuller explanation of the meaning of 'sic':
Square brackets are most commonly used around the word 'sic' (from the Latin 'sicut', meaning 'just as'), to explain the status of an apparent mistake. Generally, sic means the foregoing mistake (or apparent mistake) was made by the writer/speaker I am quoting; I am but the faithful messenger; in fact I never get anything wrong myself. Book reviewers in particular adore to use sic. It makes them feel terrific, because what it means is that they've spotted this apparent mistake, thank you, so there is no point in writing in. However, there are distinctions within sic: it can signify two different things:
1) This isn't a mistake, actually, it just looks like one to the casual eye.
2) Tee hee, what a dreadful error! But it would be dishonest of me to correct it.
Depending how "sic" is used, I believe it has another meaning one that is often used whereas sic is on brackets such as the following :
"But he has handsome words of praise for Pakistan President Pervez Musharraf. The US has seldom found an ally better than Musharraf...[sic]"
The used of sic above refers to a quote ~ sic is used to "quote the quote" meaning "said in content"
Im not saying that is how the network used it ~ Im just saying that [sic] has another meaning.
