Nugent didn't call for Obama to be killed, instead he threatened to do it himself and that is why he had an interview in the first place.
Nah, it was probably more like:
Nugent to Secret Service: Yes sir,... uh no sir,...I'm sorry sir,...I really didn't mean it sir, .... pleeeeaze sir, please don't arrest me I got kids to support, <real tears start flowing> PLEEEEZE I'm beggin....have pity,.... <****s himself> PLEEEZE I promise, I'll never threaten Obama again < on knees sobbing> plllllleeeeezzze have mercy on meeee, I I I didn't know what I was sayin, <praying> I, I, love Obama, really, I was just foolin, please, please, I promise I won't do it again...... what? You're going to let me go? <wipes tears> Really? Oh thank you sirs, really thank you thank you. I love you guys. <hugs Secret Service agent and they leave> Phew, that was close.
