Game Of Thrones: 20 Best Internet Reactions To 'The Dance Of Dragons'

How exactly did nobody notice the vast amount of gold masks that must have been needed to cover the faces of the Sons Of The Harpy for their attack? Have they got their own smelter and forger? Wouldn't there be some trace of it?

Also, does nobody perform body searches when entering this sort of event. If you so much as smell like you're trying to bring vodka or a passive aggressive sign into a football match these days you get instantly banned, but these revolters are able to bring their masks and weapons in unmolested? 

Why is nobody concerned that the violent protesting that has ALREADY been happening (and which has lead to the death of the queen's closest advisor) might rear its head at a well publicised public event? Clearly they didn't care enough to bring a lot of the Unsullied for protection.
