WOW,
I am aware of the reprecussions if you go to the police and I still stand by my statement.
I would not want to live in an area where buillies (or Sikarim) rule the roost, I would consider it an honor to be kicked out from such an area.
Not to be racists, but if you lived in an area near a yeshiva, but there was a vicious anti-semetic gang that lived there too and terrorized residents including yourself, would you stay or would you go.
