RE: Crystal meth or SHABU as it's known in the Philippines...in "pursuit of happiness".
Unwarranted aggression is what the government is guilty of in the war on drugs and other matters. If I am caught with an illegal psychoactive substance or with a gun in the Philippines, I am kidnapped (i.e., arrested) and caged by this gang called government, even if I haven't done anything wrong. That is unwarrated aggression against me.
And it's not only non-violent drug users/dealers who are aggressed against by government; it's also people who aren't involved with drugs, but are framed. Case in point, Damien Berg: http://themaharlikan.info/world/australian-man-ill-never-go-back-to-the-philippines/
Anyway, as I've said before, murder and rape need to be dealt with on their own accord. The fact that some users of illegal drugs murder and rape people doesn't justify drug prohibition or the criminalization of all drug users. Since some alcoholics murder, rape, and assault people, should you be criminalized for possessing or consuming alcohol, even if you haven't done anything wrong?
