Umm...that would depend on the charges leveled against him.....state or federal. And btw...I do not believe anybody lost their life, correct?? So, I don't think he can be executed even by federal law for "attempted homicide", but I may be wrong....
I'm no lawyer but I would think under Federal law there would be something you could get a terrorist the death penalty even if their attack didn't actually kill someone. All it takes is the political will to do it.
Won't happen under anyone. Federal Law has punishments established and they don't execute unless the act results in death. Punishment would be Prison for NO MORE than 35 years. (c) Penalties.— (1)Penalties.—Whoever violates this section shall be punished— (A) for a killing, or if death results to any person from any other conduct prohibited by this section, by death, or by imprisonment for any term of years or for life; (B) for kidnapping, by imprisonment for any term of years or for life; (C) for maiming, by imprisonment for not more than 35 years; (D) for assault with a dangerous weapon or assault resulting in serious bodily injury, by imprisonment for not more than 30 years; (E) for destroying or damaging any structure, conveyance, or other real or personal property, by imprisonment for not more than 25 years; (F) for attempting or conspiring to commit an offense, for any term of years up to the maximum punishment that would have applied had the offense been completed; and (G) for threatening to commit an offense under this section, by imprisonment for not more than 10 years.
All they have to do is lock him up on a cell block with the Aryan brotherhood. You can then kiss his ass goodbye.
Seriously though, a couple hundred thousand refugees here, a couple thousand refugees there, another Electoral College vote for the Dems here, another Electoral College vote for the Dems there..... At this pace two things will happen. NYC will become the next Beirut and there will never be another Republican president again.
