At Knifepoint

For example, an ability that triggers when you cast a spell that targets an opponent will trigger at the same time as an ability that triggers whenever you commit a crime. Those abilities can be put on the stack in either order (if you control them both), and they’ll both resolve before the spell that caused them to trigger.

The spell or ability that constituted a crime doesn’t have to have resolved yet or at all. As soon as you’re finished casting the spell, activating the ability, or putting the triggered ability on the stack, you’ve committed a crime.

Creatures that deal first strike combat damage but lose first strike before regular combat damage is dealt won’t deal combat damage again unless they have double strike. This means you can’t have At Knifepoint leave the battlefield to have your outlaws deal combat damage twice in a turn.
