That last line made me hate Ness
Reporter: Word is they're going to repeal Prohibition. What'll you do then?
Ness: I think I'll have a drink.
So you broke every law in the book, killed dozens of people, endagered the lives of countless innocents, risked the lives of your family, saw two of your friends die, all to enforce a law you didn't care about?
That glib remark made me hate that character. You might say he upholds the law without questioning it, it's not his place to decide which laws to uphold, he's a faithful government servant. Except that he isn't and he does choose which laws to uphold and which to break (including some fairly important ones about murder).
You might say he was justified because he took down Capone, but that is *beep* Capone was only as powerful as he was because of prohibition. That final line makes Ness look like a power mad, unthinking, murderering, contemptable *beep*
