I've just been spending hours in the demo, it's so much fun. I was messing with all of the game mechanics as much as I could, they go pretty damn deep. I was able to frame a gangster by shooting him and running away, and as the cops arrived I holstered my gun and they arrested him, but he resisted so they killed him
Another time I robbed a store and ran away, about 10 minutes later I was passing by, and I noticed 2 police men inside, so I strolled in and the conversation between the cops and the lady behind the counter ensued.
"You called the police ma'm?"
"Yes we got robbed!"
"Ok can you give us a description of the suspect ma'm?"
"He was DANGEROUS okay, I was concentrating on staying alive!"
"Actually.....he looked a lot like that gentlem.....OFFICERS, that's him!!"
Then they arrested me

. But I found that awesome, it just shows how deep into the mechanics they've gone to get the most immersive singleplayer experience possible.
