The usage of "sic" in writing? thread explains that:
[sic] is used when quoting another to say, "this is not a typographical, spelling or grammar error on the part of the reporter; rather, the error was in the original, and we're quoting it without change."
Now, I just read a news article with this excerpt:
The documents also show IT workers for Platte River Networks referred in an internal work ticket to “the Hilary [sic] coverup [sic] operation." A worker later said the term was a joke.
"[sic]" indicates that there is an error. Yet, the Hillary coverup operation is perfect English and does not have a typographical, spelling, or grammatical error.
So, "[sic]" is there because this author thinks that there is an error in meaning. But, not every author would put a "[sic]" in that quote. So, since when did quotes become alterable by an author?
In professional writing, do author's have the prerogative to insert "[sic]" into quotes based on the author's interpretation of what the speaker really meant to say? Isn't a quote a quote? Isn't that what causes political gaffes?
