Imagine a world where the public as a whole had convivial relations with the police, because they weren't so many people worried about getting arrested for drug violations. Imagine a world where the massive resources dedicated to drug enforcement could be directed toward solving, preventing, and obtaining convictions for murders, rapes, and so on. Imagine a world where violent criminals could not so easily turn to drug dealing and drug cartels to take in easy money to support themselves and gain power. Imagine a world where police corruption is much less common due to diminished presence and wealth of drug cartels.
I, for one, would like the opportunity to live in that world.
