Amen! And add to it that 'possession' - like medieval 'being possessed' is impossible to prove as a matter of fact. Possession is a claim - it only exists when a person makes that claim. If such claim is not made - possession ceases it exist, and hence cannot be 'proved,' at least by rationals means. That something is found in the area I control, like the basement of my house or the trunk of my car - does not mean that I 'possess' it for it could have been planted there by someone else.
BTW, many Eastern European countries, whose legal systems were based on the Napoleonic code, did not prosecute possession, but distribution and 'public' use of controlled substances. That is, if the stuff was found on me that meant nothing in court unless the cops could prove that I either manufactured, stole or bought it, or when I smoked that in front of someone else.
That tells me that EE legal system was based on more rational premises than the US legal witchcraft. Substitute "drugs" with "demons" or "Satan" and you will see that the so-called "justice" system in this country is not that much different from medieval inquisition - both resting on the reified concept of 'possession.'
