Anyone bitten by ~~a wild~~ an animal should be treated for rabies. To wait for the animal to be tested, quickly or slowly, is just foolish. This animal could have been quarantined and observed without any danger to the bite victim.
edit: the animal needn't be wild, just as this one was not.
LiDAR can be done with different wavelengths. It should be possible to make one that can see through rain and snow.
