Secondly, in no other part of criminal law or public health do we dismiss effective policies because they're not 100% effective. Do we not advocate condom use because not everyone will practice safe sex? Do we not vaccinate because vaccination is not 100% effective or because not everyone gets vaccinated? Do we not ban narcotics sales because "the criminals" won't follow the laws?
The dishonesty and inanity of these arguments is mind-boggling.
