Getting a leg up on the competition

You would think before committing a crime, say...stealing an ATM...the people would go through a checklist.

Let's see...vehicle has gas? Check.
Vehicle starts when needed? Check.
We know how to get to the location? Check.
We have a get-away plan? Check
We have tools to loosen theATM? Check.
Tightened up my artificial leg so it doesn't fall off when trying to make my get-away? Che....oh, smurf. Now I am a criminal.
