Why is "not necessarily a crime" but "not the norm" allowed

[BigmanPigman]

to be the excuse for most of 45's actions?

1. It's a description.

"Excuse" is in the mind of the hearer.

2. Investigations sometimes start with "not necessarily a crime" but "not the norm"

For example:

On July 1, X took out a $500000 life insurance policy on his wife: "not necessarily a crime" but "not the norm"

On July 2, July 3, and July 4, X told various friends at the bar he planned to go fishing for a few weeks and asked them to look out for his wife, who he said he was very worried about: "not necessarily a crime" but "not the norm"

On July 5, X flew across the country and rented a car

On July 19, X returned the car to the rental agency (having driven 5000 miles according to the odometer) and flew back home: "not necessarily a crime" but "not the norm"

On July 24, X told his friends at the bar his wife seemed to have gone somewhere while he was off fishing: "not necessarily a crime" but "not the norm"
