I don't think you're reading those numbers correctly. The highest crime per capita is in Alberque, New Mexico, the 32nd largest city in the US, and that list is literally the crime rates of the 100 most populated cities, not the 100 cities in the US with the most crime.
Which small cities, in your opinion, are more dangerous than, say, Albuquerque? How many chances, say, a high-tech professional has to regularly find oneself in such a city because his company offices are located there and they have no choice but to go there regularly?
