yn0t, why is that so upsetting to you? Dogs can be as brave or as cowardly as humans. They only choose the bravest to be police dogs, the kind who would naturally defend others with their life. Dogs are pack animals, with a clear rank and of the opinion that the lives of those that are higher are more important. This is their innate nature.

A dog risking its life to save a police officer or civilian is a noble thing. Carelessly or callously risking a noble animal's life, on the other hand, is disgraceful. Because it is more likely to give its life for someone else, you should be very careful about putting it in a situation where that might be necessary.
