Education is the way forward and this should also apply to roadblocks.

Running logic by the current state of affairs, drivers are stopped at roadblocks upon 'reasonable suspicion' and they and their cars are searched for evidence of controlled substances and the sobriety of the individual driving the vehicle.

The degree of the authority's power to search the vehicle, as has been brought up by other writers, is of course unfathomable. Authorities should rea-lise the vast majority of people are aware of the effects of drink-driving and would have agreed upon a designated driver.

Most of the people do not deal in illegal drugs but are just commuters waiting to get home from night shifts or nights out with friends.

I would thus appreciate it if the authorities would allocate more funds towards educating the public on the effects of drink-driving and the use of illegal substances rather than squandering taxpayers' money on roadblocks, which only serve to irritate the vast majority of commuters.

Although, in principle, I agree with Thomas Lofaro (The Sunday Times, April 4) that the police and the Armed Forces are dedicated professionals, I have my reservations about giving authorities irrational power to boss about the average Joe.
