We need to completly re-vamp how we police in the western world.
For me, after you get arrested for DUI after blowing a zero but cant stand on one leg because you are nervous, I have lost all respect for police in general.
We are told that there is a drug war and that it is being lost. It has all but been surrendered. Persons can smoke pot quite publicly on bar patios and other places where it can be smelled from the street and police never conduct a "raid".
Yet just because you blow BELOW 0.08 (the nationally mandated BAC on the states, imposed through highway funding) does not mean you are "free to go" or "innocent" of DWI. It's a financial shakedown racket for the cities/counties/courts/lawyers/insurance/politicians.
If the same standard was applied to drug possession and use, there might actually be a "war on drugs" being waged.
And watch out, persons in Utah want the BAC lowered to 0.03 and in Sweden it is 0.01. Neo-prohibition, here we come.
