That's absolutely crazy

It looks like they had some kind of death wish and I should probably garner some kind of sympathy for the pair, but running out in front of innocent drivers who could also be seriously hurt or killed as a result is a big no-no.
I don't think the police should be judged so harshly though. When the police arrive the pair seem fairly calm - you're not exactly going to expect people to run back across the road from where they came. The women who then does manage to run back across after being hit can't exactly be hand-cuffed because she's just been struck by a car!
"Madame, please put your broken arms behind your back so we can cuff you. kthx."
