What sense does this make?
To recap: guy and girl go out one night to "shine" deer. ("Shining" deer is the illegal practice of hunting at night using a car's headlights or some other light source to locate and freeze deer)
Guy claims to mistake girl for a deer, shoots and kills girl.
When picked up by cops, guy is incoherent and stumbling around because of "multiple prescription medicines."
Guy gets 2-1/2 to 5 years in jail which means he'll be out in about 2 years.
For killing someone.
Thanks to the NRA, killing with a firearm has been largely decriminalized.
