Backtracking to see if I can get other paths.
If you tell Arnie not to come over at the haunted house, then proceed to delete the footage and surrender, unless you snark at the cop, the game will lock up after you use the brush on your handcuffs.
There's something wrong with the handcuff timer, too. I reckon it's supposed to run so the game will do something if you forgot to pick up the item you're supposed to pick it with, but it looks like it will only run if you snark, and nothing happens if it runs out. Ergo, if you don't have the brush, you're going to have to reload.
If you're wearing any of the three costumes you can buy at the carnival, the cop will still say you had no costume. Actually, if you were wearing the default disguise, he says you had no costume, too.
If you stay silent or confess, after the cop leaves the room, the dialogue for snarking plays, and you get the prompt for getting the handcuffs off, but as previously stated, the timer won't start and the game locks up.
Same thing if Arnie's with you, except the game can tell if you're wearing a costume now. You can talk to Arnie in the cell, but one of the options was locked for me because I wasn't in negative standing with Arnie. Not sure how to get on his bad side.
I can't see any more options that might unlock a different path, so I guess I'm done.
I can't believe this guy used to charge for this. Well, it's free now, so I guess it saves me the trouble of getting a refund.
