already, at other previous stops on the same tour resulted in injury. They knew that their own methods were causing great risk and they did not alter their own methods. Foreseeable.

In a country where Westboro Baptist has done thousands of hateful stalkings of Jews and LGBT people none of which resulted in violence, how do you establish that it is 'predictable' that hateful events will get a violent response? Do you expect to employ an argument that some groups are less stable than others and thus one must hire extra security, or that some groups deserve protections LGBT and Jews do not?
Every day in the US, there are anti gay billboards, pickets, books, sermons, rallies, statements to the press, church marquees with anti gay messages. The Klan has had many rallies without being shot at. Nation of Islam holds big events in which gay people and Jews are openly attacked in very brutal terms, they are not targeted with violence.....so how do you establish that hateful invective creates foreseeable violent crimes if so much hateful invective is so commonly practiced without any violent reactions?
