San Antonio has (had?) a reputation as a rough city. I dont think the statistics bear that out. Then, or now.
Having said that, San Antonio damned well has bad areas. I am a street cop, I know a thing or two about crime and bad areas.
As an opinion and being well traveled, places around Cleveland or Detroit or parts of a lot of other cities are far worse than the worst parts of San Antonio. Kind of like Boston, in San Antonio, I will go to the worst parts of town, in the day, to do business or eat. (stopping at night is another story...) Even in broad daylight, I would not stop in East Cleveland if I was on fire and I saw a watermain spewing forth.
