I would disagree with you, sir. Driving is not a right in this country. Driving is a licensed activity. It is a privilege, so the example you give with the airport is irrelevant.
Also, the courts have already dealt with the issue of whether a government can require random screening to enter a public building. The last time I was here the security seized my shaving cream three times. I was searched. I was scanned three times. We, in this room, believe that the state interest in protecting parliamentarians justifies random search of my person and my property. The courts have addressed this issue and upheld random screening and searching for entering public buildings and courts.
If you look at the statistics on deaths and injuries in Parliament and in government buildings and you look at the deaths and injuries in terms of roadways, there is no comparison. I would suggest to you that the state interest, in terms of random breath testing, the number of lives we would save—probably something like 20% reduction in traffic deaths and injuries—warrants that interference with the right to be free from unreasonable search and seizure. You're right, it is random search, but drivers are already subject to random stopping. Drivers are already subject to random search. Police officers can demand to see my licence and insurance. That's a random search.
The state interest in making sure you are sober is greater than the state interest in making sure you have your insurance and licence with you. That is the reason why. As between random breath testing and 0.05, the evidence is clear. The random breath testing will have a greater impact on reducing deaths and injuries.
