Charles Starkweather killed a gas station attendant on 12/1/57. On 5/5/58 he went to trial. On 6/25/59 Charlie fried in the Nebraska electric chair. That is 13 months between trial and execution.
What are the chances Muhammed will be around to celebrate New Year, 2017?
I think you left out that Charles Starkweather killed 11 people, not just one, but your point is valid still the same.
