The personal connection and loyalty of friendship, and even just working-relationship, is stronger than internal policy and even serious laws which are in the Øygard case, there to protect children and make it easier to prosecute offenders.
This has two notable symptoms or rather disabilitating effects on companies and individuals : for the first it leads to " we are good old comrades, and we will fix this without stressing about it" and the related side effect of level of trust placed in comrades to actually fix things. Secondly as in the case above, it means that rules and even laws are there as far as they don't go over the power of personal relationships and respect for long term connections.
It applies to many aspects of life, but expecially unfortunetly personnel policy which is quite lacking or just lip service to the rules and laws when it comes to loyal employees getting their way at the expense of others!
I have been moved to a rather back water job for the moment, same pay and conditions, because of this chummyship. Seen it all too often.
