"Wouldn't it be better to have a watertight law designed to catch the guilty, rather than a press release law designed to catch the headlines?"

This quote by William Hague is describing the importance of having laws that work and well-crafted, instead of laws that are quickly produced in order to acquire public attention. He is recommending that it is much better to have laws that are developed to capture the guilty, instead of laws that are created for the sole purpose of acquiring headlines. This suggests that laws must be created with the objective of providing justice and safeguarding the public, instead of merely to acquire public approval. Hague is stressing the value of having laws that are well-thought-out and reliable, instead of laws that are developed for the sole purpose of acquiring public attention.
