13. Yes, it is. But what about the balance of benefits/costs using 'lists' to invoke prior restraint?

Are all lists equally good? Do they all use the same criteria and balance the same costs?

Is cost/benefit analysis even reasonable? Do the costs matter is relative cost and relative benefit an issue or should this be more an absolutist black and white sort of thing?

If anyone is at risk should we incur whatever costs to prevent it? Is cost nothing and security everything?
