1. we are talking about sakanas nefashos. since september, 23 Jews have died, 19 in the West Bank. So yes, Yerushalayim is very safe, and Tel Aviv (your example) is certainly safe.
2. your numbers about black on black crime are also off. Roughly half of all murders are by whites and half are by blacks, according to BJS stats for the past 30 years.
And just so you know, 57% of all religious hate crimes in america are targeted at Jews. for example, I know a girl whose brother got beat up by a black gang on the street just a few months ago, for being Jewish.
