More crime is not the only difference Americans notice in large cities. There are also different laws regarding decency, civility, and cleanliness. Unfortunately, manners and traditional customs are rarely, if ever, practiced.
The rural meth head problem ain't so nice neither. I hated it when my house was stripped of copper pipes, wiring, and they even stole my zero turn! Drove it seven miles down the road to the next town over and nobody in the area blinked an eye.
