explanation here, that it's one thing that provoked this that you could end up with someone with mixed motivations. certainly, the targeting of this workplace now is less mysterious. since he worked there. so he wasn't confused about where he was or what he was hitting or what he was attacking. he knew exactly where he was hitting and why he was hitting it. we don't yet know why he was hitting it. but he clearly did. >> that's a very good point. >> you know, if it was clear cut terrorism, it would be rather odd for a guy to shoot up a center like that. rather than making a big public display, like the boston bombers or what occurred in paris. it would have been a much more grandiose exhibition. the fact this was very targeted. the fact that, supposedly he walked away angry, and connect that, we still need to know
