EDIT...
just realized you are in Israel i have no clue on the law regarding street photography in that country
my reference is for the UK and probably have no bearing on the laws of your country


there is this misconception that we have a legal right to photograph more or less anything in a public place which isn't quite the case the reality is there is no laws to stop you as long as your not causing an obstruction or harassment
the other obvious is not photographing what is classed as sensitive buildings or landmarks
as far as photographing the general public from a public place again there is no law to stop you and in this country there is no legal requirement for a model release document although other countries might need one if you plan on publishing elsewhere in the world
