So where do we go from here?
Can Americans still hold sporting events the way they used to be, after an attack like the one in Boston occurred?
The answer is probably yes. It's not the first major attack either at a sporting event or in a densely-populated area, and eventually things went back to order - albeit with heightened security.
But Gary Tanguay, Lou Merloni, Fred Toucher, and Kevin Paul Dupont discuss what comes next in terms of safety and security at sporting events. Can we feel safe? Are we taking a big risk by attending these events? Will "rolling rallys" stop?
The four discuss these things and more, so check out the video.
