I’ll be honest, after watching the last deer I shot with a bow suffer, I’ll make sure I have my 1911 on me me to finish the job.
I’ll take the damn ticket.
What you do is ask for a jury trial...if it's worth it to you. No different from hitting a deer/animal in your car on the side of the road and dispatching it to prevent suffering. Technically you might be in violation of the law but under the right circumstances a jury wouldn't find you guilty.
