>> is there something about a new convert that is more prone to this? we've seen this not just with radical islamist. if memory serves me, you know, there had been other shooters of world leaders by people overseas who have been recent converts to other relig gions over the year >> i think there has been a number of studies about the zeal in which somebody comes into a new faith and that may not be relevant in this particular case but of course, that is an issue in a lot of cases and i think in the isis recruitment patterns, they are looking for vulnerable individuals. and so whether it's the risk factors they are offering from a a ail nation, they offer them a path that involves some form of religion and people gravitate to that for a sense of belonging and social network.
