Absolutely. God forbid that anyone should do something so dasterdly and against the law, even if it is to protect the lives of his or her loved ones. Myself, I won't even kill rattlesnakes on my property unless they bite someone first.
You may wish to milk the rattlesnake first. I understand that there is a shortage of anti-venom at this time.
Rattlesnakes, along with any other venomous snake-copperhead, coral snake, etc-are offed here-too many chickens for them to kill and livestock for them to bite-that gets expensive, and there is the danger of humans and pets being bitten. Rattlesnakes are not wasted by me or mine, either-the rattles and skins sell well to tourists for belts and hat ornaments, and marinated rattlesnake grilled over mesquite or hickory wood is a delicacy I never turn down...
