"Is the chief on your ass？" —— James Patterson "4th of July"
Would you let me know what does the sentence in title mean? The context is:
"On the other hand, with all the potential snitches crawling through the Tenderloin District, all we have is one shitty lead."
"It sucks, Linds," said Cindy. "Is the chief on your ass?"
"Nope," I said. "As the killer says, nobody cares."
Also this one. I have no idea what's the meaning of "cracked" here.
"She says, 'no problem,'" Cindy cracked, pointing to Jill's empty seat. We lifted out glasses and clinked them together.
