What do the following lines from the passage mainly reveal about Officer Bockert?

"Come along," Bockert said, "I will find your trunk for you." We all went together, Mrs. Stanard, Tom Bockert, and myself. I said it was very kind of them to go with me, and I should not soon forget them. As we walked along I kept up my refrain about my trunks, injecting occasionally some remark about the dirty condition of the streets and the curious character of the people we met on the way. "I don’t think I have ever seen such people before," I said. "Who are they?" I asked, and my companions looked upon me with expressions of pity, evidently believing I was a foreigner, an emigrant or something of the sort. They told me that the people around me were working people. I remarked once more that I thought there were too many working people in the world for the amount of work to be done, at which remark Policeman P. T. Bockert eyed me closely, evidently thinking that my mind was gone for good.
