Perhaps the simplest solution is the most visible?
During the work on my site http://www.hemp4victory.com I have managed to prove the drug laws to be invalid under US Code
Officials have no right to take life, freedom, or property (life/murder, freedom/enslave, property/theft). Drug laws are invalid as they prohibit ownership of property & violate a right to contract. They’ve slowly increased power of the police to violate other rights of privacy, further property rights infringement procedures where the state keeps the property even if there are no charges pressed against the person the property was stolen from. As the constitution protects our liberty, making it illegal to own property is in conflict to the constitution making these laws invalid. Any enforcement of these laws is punishable under US Code Section 18 Title 13 Sections 241&242
Since you own your life, you are responsible for your own life. You do not rent your life from others who demand your obedience. You are also free from the chains of enslavement and cannot be forced to do anything against your will. Any laws that deprive someone of their unalienable rights to life, liberty, and the pursuit of happiness by limiting their choices is in direct violation of the concepts of liberty, and as liberty is a protected right under the constitution these laws are invalid.
