Hang on "my friend did not commit crime. he was caught in selling the liqour...".

Assuming he did not work in QDC, then of course he committed a crime.

Alcohol/Liquor can only be sold (outside of certain hotels and restaurants) by QDC to people with a Liquor Permit.

That person must take it directly to their place of residence.

It CANNOT be sold on, it CANNOT be given away, it CANNOT be taken be transported (including) by foot) from the residence.

Therefore selling the liquor is illegal and breach of Liquor Permit Terms. Your Friend DID a Commit Crime
