Another dog murdered by violent cops

Police came to search her house because they said her grandson was involved with drugs. The woman says her grandson hasn't lived with her for 12-years. She asks the police if she can put her dog out in the backyard or in the bathroom. They tell her the bathroom is fine. So the dog is shut up in the bathroom. A cop opens the door to the bathroom and shots the dog, claiming as they always do, that the dog attacked them. Why is it that in case after case, other eyewitnesses to such incidents have stories that almost never correspond with what the cops say? Could it be that cops routinely lie? I think the answer is a resounding yes.
