Let's go shoot the *** out of some damn destinies.

ANA:

The junior officers program is the chief's priority.
It encourages children to explore a career in law enforcement.

JACK:

Okay, but they're 10. They're probably also exploring careers as superheroes.

ANA:
Okay, Bailey, look, I've got work to do, okay? So please go now
and be inspired by, you know, the light in their eyes.

JACK:
With all due respect, are you absolutely sure you want Dan Stark...
Dan Stark...
Dealing with children?
No offense.

DAN:
None taken.

ANA:
Jack, don't ask me how, but junior officers that work with Dan Stark...
become cops at a rate that can only be described as...
Alarming.

jACK:
Really?!

ANA:
Really.

DAN:
It's easy. See, you deal with kids the same way you deal with adults.
It's just, they're, you know, short and broke.
Come on, partner.
Let's go shoot the crap out of some damn destinies.

What does it mean let's go shoot the crap out of some damn destinies?

thanks....
