Weird Wednesday: Death Dealer, Death Delayed

The shotgun Lee had stolen from that guy
Who'd beaten him at poker long ago,
Turned out to be -- and this is not a lie --
Miraculous. It didn't take long, no
To see how each foul crime Lee undertook
Seemed doomed to end with discharging that gun
Into someone that knew he was a crook
And sought to foil him. A few shots, then run
And leave his adversary dying there
Was all he had to do. And when there came
The medics, drivers, doctors, those who dare
To steal death's victims, it would end the same:
All efforts that were made for to extend
Lee's enemies lives postponed Lee's own end!
