I don't think AnimalMuppet is suggesting that there will be pressure from outlawing searches that are Very Useful for enforcement. I think the suggestion is that the pressure will come from outlawing searches that are Very Useful for rescue.

Suddenly, many more searches (that fail to find a given child) are happening.
