User blog comment:Morgana High Priestess/Which reign is better: Uther's or Arthur's?/@comment-3012002-20130120111653/@comment-5674726-20130120131346

''Yet he knighted commoners without his father's permission. I think this was out of line and very disrespectful towards Uther.''

He even specifically said that he was doing something his father wouldn't approve of. You're right that it was disrespectful. If it meant that much to him, he could have promised that he would knight them once he was King, and entitled to do so.

On the subject of the knightings: Were the four men actually knighted under Camelot's laws? Arthur didn't have the authority to knight them and, if he didn't repeat the ceremony once he was crowned - not an option with Lancelot - would it matter that he did it at a time when, technically, he wasn't even Crown Prince, let alone King?
