There are multiple facets to this question. Would I want law enforcement to catch, for example, every murderer? Yes I would. On the other hand, we have in the US things like the fourth amendment prohibition against unreasonable search and seizure.
If these laws are used to sidestep prohibitions on what government is not allowed to do, i'd say they are a bad thing. If they are used to enforce bad laws, we need to get rid of the bad laws. If they are used to help enforce laws we all agree are good, that seems like a good thing.
