I came across a blog and the title reads :
Dadri lynching too minor a incident for PM to speak: Modi minister
I know that at times, media use 'Headlinese' for writing titles in which they tend to omit articles. But then, here, to my mind, article should be 'an' instead of 'a'.
P.S. Original blog has changed the title now and it reads 'an' instead of 'a'.
