In Washington state, US, there's a real-life law stating it's illegal to kill bigfoot and other sasquatch-like creatures.

Bigfoot fervor resulted in two Sasquatch preservation laws: the 1969 Skamania County Ordinance no. 6901, later amended in 1984, and the 1991 Whatcom County Resolution No. 92043. Each law purports to protect a creature that, if it does exist, is obviously endangered.
