Are you for real? This person may have saved up for the trip of a lifetime and why not walk her little one through the arches. Or have you thought that maybe they live somewhere around there or she might have been coming back from a part time job and she cuts through. There could be endless reasons, at least she didn’t Molly coddle the little one and start complaining to the police, nope she held her head high and carried on walking. Buska was just stating what he filmed, that the Guards shout made the baby cry. Some will some won’t. It’s not like the cry was annoying people. Just because you have a child, don’t stop enjoying things and getting on with life, it’s way to short. She could even have been a soldiers wife/partner and like to walk through, they may be away on active duty or God forbid, no longer with us and it helps her feel close to them. So many possibilities as to why and so far I can’t think of a why not. Just my opinion.
