The Crusaders attack the northern part of Jerusalem because it was the closest part of the destination to them, and to achieve 'surprise', it must be quick, and so they couldn't wait out a siege... hope this helps
Anyone should have the right to express their views verbally. if a censorship was put on someone expressing their views verbally, no matter how ridiculous and offensive they sound, it would be unconstitutional and could lead to further restraints on the freedom of the people.
