you've a 50/50 chance of getting caught.
either they're watching who's downloading those particular files or they're not. you either get caught or you don't, and if you do will everyone who says 'you have very little chance of getting caught' all send you cash to help with the hefty fine? i doubt it somehow.
the reality of the matter is people DO get caught, not just people downloading 30 films a day, i'm talking about everyday people using insecure peer to peer filesharing programs.
if you knowingly break the law that's the chance you take, whether you consider it to be worth the potential consequences or not is entirely up to you.
on a sidenote, smilelifeisanadventure's answer is rather odd, which individual pays $17 for a cd then pays $50 million to go and see a film? the net sales value of a music album from the hundreds of thousands of people who buy it generally adds up to a *little* more than $17 in total sales - that figure will also run into the millions otherwise 50 cent wouldn't be wearing all that 'ice'.
how naive can people be? if *i* can easily see your IP address when you're downloading a file you shouldn't be why wouldn't someone like the mpaa or riaa with disposable cash for automated logging systems be able to?
fool yourselves as much as you like people but if you get busted cos you don't consider it illegal just don't sob like a lil biatch lol
