There is sure something amiss when accidents occur.
Let me try to think of examples.
When something falls off the building and injure someone as killer litter.
A drunk man knock someone in a car accident.
A drunk man got hit in a car accident.
When you leave you gun on the table and someone take it to kill another person.
When you accidentally put your stuff lying around and it fall to pieces.
So in conclusion, don't think of excuses to save your ass.
There are no accidents in this world.
