Marty did not set his car on fire, he placed some clothes on the dash and set them on fire.

I'd like to know how the law knows that Marty put a gun to his head and said, "You won't take me alive" when he was sitting in his truck in the garage with the garage door closed.

Also, Marty missed his court date on June 2, because he was in jail. He was arrested on June 1 while he was driving back to NWA for his court date the next day.
