What is the word?

What is the word that would best fit the following description:

"A word that brazenly attempts to convert a negative fact into something positive...and succeeds"

"Euphemism", "equivocation" etc fall short of what I looking for.

Whatever the word may be, it should apply perfectly to the latest idiocy of modern Indian cities, specially Bangalore: "Signal-free corridors". The suffix "-free" is cleverly used to imply that the prefix is something undesirable; like cavity-free teeth or rodent-free houses.

For instance, the BJP manifesto for the long awaited Bangalore Municipality elections (no municipal elections for the last 7 years, city's being run into the ground by bureaucrats and commercial interests) promises that:

-93 roads will be widened (=> more trees will be cut)
-20 parking complexes will be constructed
-city will be made crime-free (note the use of the suffix "-free"), and finally:
-all major junctions to be made signal-free (note the misuse of the suffix "-free")

Free from whom, I wonder? From all the rodent-like small people called pedestrians who are cheap enough not to own Corollas and Scorpios.

It is just amazing how, by just picking the apt word, they have managed to convert an absolutely crucial piece of equitable road planning into something extraneous and evil: something that people will actually vote for.

So I wonder: what is the right word?
