Teaching and protesting  is not effective. There are still people who dont respect different races and cultures. Why don't we imprison them? It is one of the biggest issues today and everybody talks about less important things. Sorry for my English.

You need to be more specific.  What do you mean by "not respecting different races and cultures"?  I don't know where you live, but in a secular democracy where individual liberty is paramount we don't imprison people for not respecting other races/cultures.  The concept of disrespect is entirely subjective and within the ego of the offended.  And in the West we don't trample individual liberty for the sake of someone else's wounded ego.

The crime rate is low, but not zero and it must, at some level be cultural rather than due  only  to law enforcement.
