I'd say that Capital were being careless leaving their counter unattended considering that there are some opportunist criminals around. But if this was theft, it was still a criminal act (although a very minor one) - it doesn't mean that Capital share the responsibility for the crime.

The same with much more serious cases such as assaults on very intoxicated women in the streets. The attacker is completely morally responsible, and the victim is not to blame for the crime, but it still isn't sensible to be out on the streets alone and incapacitated in places where there is known to be violence. I think the two things sometimes get mixed up (criminal activity and a reasonable degree of self-care) and they really aren't the same.
