Silent Hill was... not a good movie...

[Dark Jaguar]

Riiight. The reality is that despite what they INTENDED for that scene to mean, it came out as ridiculous. No one in the audience understood the reasons for that sudden "I'd better go!" thing. She had no reason at all to think she would be arrested, she barely had reason to think she might get a ticket, and was the risk of actually being PUT in jail and losing her child really worth a, at the MOST, half hour delay? All it ended up doing was crippling her in that town anyway, when otherwise she might have had an ally give her a gun early on, perhaps in some coffee shop.
