| Quote #10
Hastings realizes that he has been used by Richard, and he has no one to blame but himself. He curried favor with men rather than embracing the graciousness demanded of a Christian. (Think of how he delighted in the deaths of his enemies at Pomfret.) Here Hastings realizes that he was walking a fatal line with Richard, and he's just stumbled to his death.
| Quote #11
The mayor of London is all that stands in the way of the common people coming to realize that Richard is tyrannically killing people. So the mayor's sanction on Richard and Buckingham's hasty execution of Hastings is important. Buckingham outright lies to the mayor, and the mayor is somewhat skeptical.
What changes the mayor's tune is Richard's manipulation. Here Richard doesn't insist that Buckingham is right and bolster their story. Instead, he asks in feigned outrage whether the mayor is calling him a liar, suggesting that the mayor's skepticism is preposterous. Again, it's that tactic of asserting one's power over the situation and making the accuser answer for himself, thereby deflecting the question from the punk who's actually guilty.
The mayor quickly corrects his position, insists that he never trusted Hastings once the guy took up with a hooker, and seems satisfied to fall into Richard's manipulation. It's almost like Richard is the leader of a club (called the royalty) and if you want to stay cool, you better believe what he says, no matter how ridiculous it seems.

Buckingham manipulates the people by making it seem like he has to twist Richard's arm to take the crown. Richard can't seem too eager, or the people will suspect him of ambition. So he has Buckingham put on a really big show, and the people are made to feel like Richard's done them a favor by usurping the throne. (On the other hand, Richard may be less powerful than he thinks, as this little scheme is pretty transparent – to us, at least.)
