This is blatantly false. I don’t like it, but it most certainly happens at other countries and not just a US phenomenon. I’ll paste some proof: https://www.ctvnews.ca/mobile/sports/brazil-police-sniper-nearly-shot-officer-during-world-cup-opening-1.1889183? https://www.dailymail.co.uk/news/article-9692301/Greenpeace-apologise-Euro-2020-stunt-horror-left-two-injured.html https://sports.ndtv.com/euro-2020/snipers-were-ready-to-shoot-parachutist-at-euro-2020-match-minister-2465542/amp/1 https://www.theguardian.com/sport/2016/feb/01/france-biggest-security-operation-six-nations-stade-italy

Also, this isn’t even how they do it. It was an ad for the tripod basically, and it wasn’t loaded. They use binoculars and not the rifle for scanning. https://deadspin.com/those-super-bowl-sniper-photos-are-real-5883525/

Hate to be that guy but also hate misinformation so had to chime in.
