Most likely that was the first and last time those two drug-users tried getting away from the police.
Apparently the Audi had been driving at very high speeds on the wrong side forcing oncoming traffic to visit the ditch and when the police got on their tail, things turned even uglier. Nobody got seriously hurt, thank god.
The photographer and other witnesses said that even though the pictures look dramatic, the police had no choice - they saw a chance to bring the pursuit to an end before someone innocent got hurt and they took it.
The photos were taken by an amateur photographer who then won a newspaper's contest for best reader's photo of 2009.
