I suspect you are implicitly trying to make the point that a hypothetical afghani neighbor is potentially a violent person. Regardless, my answer is the same.

Violent people live everywhere. Many of them are native-born Americans, and are already my neighbors. Many native-born Americans even actively support clearly anti-American and fascist political policies.

If my neighbors commit violent acts, I expect and assume the law will deal with them. Until they have demonstrated otherwise, why should I presume that any possible neighbor is violent?
