You guys always like to run with the prefatory part of that statement. "Criminals will get guns anyway, so gun control only serves to meaningfully disarm the citizen base" was never a quote about how law enforcement fails to achieve perfection (although I agree they are far from it.)
This comparison kinda relies on the implication that not only all crime is equivalent in moral value but that all crime should be enforced at equal levels, neither of which are true. It's a lot worse to kill rape or rob someone than it is to break gun possession laws, which are arguably victimless crimes.
