So he starts by arming himself: fair enough, if you're going on a spree you'll need a weapon. A Taser? Obviously he doesn't want to accidentally kill people. That's forethought.
Then he steals a shirt: okay, maybe he wants a memento.
Then he burns the shop down: Well... that would destroy the evidence.
Robbing people, tasing one: Well, he needs money... and at least he didn't shoot him with the pistol.
Carjacking a cab: so he escapes...
Buying food with stolen credit cards: Obviously arson and robbery build up an appetite.
Buys $199 of items from Wal-Mart: I really want to know what he bought and why he didn't go for the full $200, for some reason.
Breaks into hotel law offices, shits on desks, smears shit on law degrees: Obviously some kind of message to the judicial system... or he's batcrap crazy.
Robs hotel guests, pretends to be female housekeeping, robs people at gunpoint while crying: Why FEMALE housekeeping? And why was he crying? Now I feel bad for him...
Then he shaves his head: Fair enough. Doesn't want to get caught. I think he might be a Crime Savant.
He crashes his stolen cab, jacks another one: This is getting very 'GTA'.
Arrested, partially submerged in a water-cooling vat: Well, he's been running around and shitting all over an office. Sweaty work. And he'd be covered in shit.
