It's because Chris Klein was driving under the influence of alcohol, from which his dosage triple the normal level allowed by street authorities and because he traveled with his own dog. But according to report, the DUI seems supporting him because of their own ideology in regards with his pet but probably not for Klein. In Defense of Animal representative stated that the arrested driver has a dog on-board so he need to cross his way for the safety of his pet.
Because of this, according to animal activist group, Chris Klein was innocent because he also needs to protect his dog not just himself although he is under the influence of heavy alcohol. And he already trying to save his dog from danger but in our own perspective, he even put it in danger, he can leave his pet before going to any party or occasion to maintain the safety of it, right?
