Motown,
You're information is simply wrong.
The central tenet of libertarianism is that the initiation of force is a criminal act.
Therefore child pornography is a crime.
Of course criminal organizations supply ILLEGAL drugs, that's the point. When you create a demand for a prohibited substance a criminal organization will spring up to meet it. There is no way for a criminal enterprise to maintain a monopoly if there is no crime involved in production. We're talking about plants for the most part, that literally anyone can grow. The resources devoted to the drug war would be better spent keeping foreign drugs out of the country(and the profits out of the hands of criminal/terrorist organizations), which is only posible with tighter border controls, which is only possible if we document our immigrants, which is the libertarian position on the issue. Hard drugs tend to come from overseas, the federal government is authorized to regulate international trade. There's no need to lock up citizens to have an anti-drug policy.
No, that's not the case. Not all libertarians and not all law enforcement. Privatization in this case is more about how the system is funded, charging criminals and those involved in civil litigation for the true costs of the services they receive. There is no support I'm aware of for giving any lawmaking or enforcement authority to one group of private citizens over another.
Never trust anyone to accurately represent the policies of their competition.
Never confuse libertarianism with libertarian socialism, which is a completely different political philosophy which Badnarik is no way affiliated with. Libertarian socialism is a fancy term for anarchy, and many mainstream political pundits conveniently don't recognize the difference.
Libertarianism is the belief that government has a legitimate role in society, that that role is to enforce the principle that the initiation of force is a crime. Since it must initiate force itself to exist and to enforce the law, it cannot legitimately exceed that mandate. That mandate includes law enforcement, national defense, international relations, and some environmental protections (you're neighbor cannot pollute your property, or public property, with impunity.) and so on. That's the root of all libertarian positions.
