Why doesn’t Jaggers worried about being robbed & what does that say about him?

Jaggers is powerful and not afraid to use the power he holds over those who might attempt to rob him.

“That’s it!” returned Wemmick. “He says, and gives it out publicly, “I want to see the man who’ll rob me.” Lord bless you, I have heard him, a hundred times, if I have heard him once, say to regular cracksmen in our front office, “You know where I live; now, no bolt is ever drawn there; why don’t you do a stroke of business with me? Come; can’t I tempt you?” Not a man of them, sir, would be bold enough to try it on, for love or money.”
“They dread him so much?” said I.
“Dread him,” said Wemmick. “I believe you they dread him. Not but what he’s artful, even in his defiance of them. No silver, sir. Britannia metal, every spoon.”
“So they wouldn’t have much,” I observed, “even if they—”
“Ah! But he would have much,” said Wemmick, cutting me short, “and they know it. He’d have their lives, and the lives of scores of ’em. He’d have all he could get. And it’s impossible to say what he couldn’t get, if he gave his mind to it.”
