Honestly this makes Israel look really bad to outsiders. It smacks of the aggressive anti-civil riots that occurred in France a couple years ago. It sounds like a fairly anarchist tactic and that these Israeli citizens are taking a page from the growing religious extremist groups which have been increasingly using violent tactics in other countries. Religious sects of Israel are beginning to court these terrorist ideologies. If the government allows this to continue then Israel may become just another unstable state in the Middle East overtaken by a violent extremist minority.
Thats my two cents.
