I totally agree we tend to overreact when things like this happen. Let's chillax and enjoy life. I remember that one said. If we give in to fear of terrorism they won. I understand that this was suicide. People need to go through psychological test and they should be asked if they've got any issues at home or financially and then be helped with advice etc.
I agree with BAs stance here and would use them again in the future if I had to.
