Yes but as Alexandra explained, only in this case - not always. Here all of your subjects are completely stationary, so you don't have to choose between freezing action (with a fast shutter speed) or using blur for effect (slow shutter speed). However even here you can't completely discount shutter speed - unless you're using a tripod there's a limit to how long the exposure can be before you get camera shake (with your wide-angle lens probably nothing longer than 1/30th, or 1/60th to be safe).
