"No realistic, sane person goes around Chicago without protection"

This quote by Saul Bellow implies that Chicago is an unsafe location and that it is not safe to be there without protection. It suggests that anyone who is reasonable and sane would take safety measures to safeguard themselves when taking a trip in the city. This might suggest bring a weapon, travelling in groups, or preventing particular areas. It suggests that Chicago is a location where violence and criminal offense prevail, and that it is essential to be aware of the dangers and take actions to secure oneself. The quote likewise suggests that anybody who does not take these precautions is not being realistic or sane. It is a warning to be familiar with the prospective risks of taking a trip in Chicago and to take the needed actions to safeguard oneself.
