The terrorism charge was so prosecutors could nail him with 1st degree murder. Otherwise the charge wouldn't apply and they would have gone for 2nd degree murder.

Under state law, murder in the first degree only applies to a narrow list of aggravating circumstances, including when the victim is a judge, a police officer or a first responder, or when the killing involves a murder-for-hire or an intent to commit terrorism.

Look, the man is a hero, but let's not post bullshit.
