I didn't find the ending plausible
Crisp threatens to kill his own kid, and Kimble puts down his gun. This is implausible for several reasons.
1. Crisp went to some trouble to find the kid. Would he really kill him? If he actually pulled the trigger, guess what happens next.
2. Not a really good idea to lay down your gun when confronted with a psychotic killer. Guess what happens next. Then he goes on killing other people.
3. Cops are told never to surrender their weapons.
4. This stupid scene has been done at least a thousand times. It somehow always ends well. In reality, he ends up dead.
