You can randomly shoot any legal deer that has wandered onto property where you have the legal right to hunt. It is better, however, if you shoot the deer in a vital area since random shooting can injure but not kill the animal causing undue suffering.
FWIW, whitetail deer are the property of the state, therefore the state regulates their kill or capture. This does NOT apply to exotic game which can be killed year round.
How's that for a random answer??
