RE:RE:OPP Approach to SWABi dont think it will need to be at the forefront and hold up in court as much as we might think. yes/no within 2 hrs. reasonable gorund for "quick" arrest for further tox screening. our gov seems satistified with their capabilities once in a lab, maybe police station, to prove time, dose, etc they simply need to bridge that gap between roadside and lab. asking police officers to double as nurses on the side of the road is a little outside their job description.
