I think the drunk driving thing was over blown.
Basically cops don't want to steal people's cars because they had a burger and a beer an hour earlier. They Checkstop for the hammered folks that clearly shouldn't be driving.
You probably will never be pulled over for drunk driving unless you are hammered and shouldn't be driving.
Speaking as a non-driver, and as someone who hasn't had a drink for about eight years(no, not a recovering alkie, just don't like the stuff), I wasn't sure what to think of the drunk-driving legislation.
Most plausibly, it was an appeal to the "soccer mom" vote. I agree that it wouldn't likely result in some mass confiscation of vehichles from everyone who had one beer before hitting the road.
That said, from what I know of cops, a few of them wouldn't be beyond using the law to go after people in personal vendettas, if the bar for confiscation is set too low. These would be isolated cases, not a stalinist crackdown directed from the premier's office, but abusive nonetheless. Some of you may know about the adventures of an Edmonton journalist with the police, after he pissed them off in his newspaper column.
On November 18, 2004, seven members of the Edmonton Police Service targeted Diotte along with then-police commission chairman Martin Ignasiak in a controversial undercover drunk-driving operation at an Edmonton bar, the Overtime Broiler & Taproom. Police were staked out in anticipation of catching the two men driving home drunk, but both took cabs home.
Subsequent legal proceedings produced evidence, including police radio conversations from that night, showing officers set up the operation because they were upset by Diotte's newspaper columns about policing, including criticism of photo radar operations.
After an internal police investigation exonerated the officers involved in the unwarranted would-be sting, then-police chief Fred Rayner was fired from his position by the Edmonton Police Commission.
In September 2008, Alberta's Law Enforcement Review Board ruled a senior police officer abused his power by targeting Diotte because the law enforcement official was frustrated by the columnist's viewpoints on police matters.
One wonders what these power-tripping cops would have done had they had recourse to Redford's drunk-driving laws.
