In a back yard in the Oklahoma community of Enville, a woman was attacked by a white-tailed deer buck. The woman escaped with some injuries. The deer remained outside her home, apparently looking for more trouble. He got it in the form of a deputy sheriff. The buck charged at the lawman and was shot dead.
The news report I've linked to describes the attack as "shocking," but deer attacks aren't that unusual. Bucks become extremely pugnacious in mating season. Mostly they duel each other for mating privileges, but occasionally they take out their frustrations on other species.
There's a greater danger than attacks, however. About 100 people a year die in vehicle collisions with whitetailed deer. The species is found in most of the US and southern parts of Canada.
