seven second delay?

[Donna Halper]

Doesn't WBZ radio use a 7-second delay on its talk shows? Tonight, on Paul 
Sullivan, around 8.25pm or so, a caller discussing the scandal surrounding 
the Big Dig, asked why some people who used to defend Matt Amorello (the 
head of the Turnpike Authority) now suddenly want to "shitcan" 
him.  Embarrassed silence and then the caller got cut off-- but it went 
over the air.  How did that happen?
