Do you see how

[Mike Hussey]

Attorney Loew says to Officer Bud, who involved in prison quarrel:

Attorney Loew: You and Officer Stensland brought the liquor to the station. Stensland was already drunk. Do you see how appearing as a voluntary witness against him......could offset the damage you've done to yourself?
Bud: Sir, I won't testify against my partner or anyone else.

Now that you understand what the expression means, you can say "Oh! I see!" It's a very common expression.
