event that you might relate to what we saw in brussels? or is this something more from somebody that had mental issues like virginia tech shooter, the newtown massacre and movie theater attacks in colorado. i mean, what really is this? and people automatically and you have to look at the terror angle at the very beginning until you can pretty much dismiss it. and then find out what that motivation and why the mental illness if that's the issue and why he got the gun that he got, when did he purchase the gun, was he allowed to, did he have a criminal record? those are all going to be looked at monday morning quarterback as the weeks go by as to what happened here. >> yeah. certainly with the terrorism issue you still have questions as to whether or not this would have or could have been isis inspired or terrorism inspired or coordinated or even directed from overseas or what have you. all right, peter ahearn, great to talk to you. thank you very much for joining us this hour.
