I think we all appreciate the light-hearted meme-ing of Kim Yeji and Yusuf Dikec in their respective air pistol events. And we all know the joke around US not winning any medals in shooting (thus far).
But the truth is sports shooting (air pistol, air rifle, or even trap) is very different from military marksmanship, and military marksmanship is very different from gun ownership in the US.
Sports shooting is about precision, control, and consistency. Military marksmanship is about shooting down the enemy efficiently, i.e. fewer bullets used per kill. Both need good trigger discipline and good weapon handling skills. But the former is about winning a competition for a prize, the latter is about winning a military battle.
But vast majority of gun owners in US are neither sports shooters nor military marksmen. They are the abhorrent bunch of idiots who think gun ownership is a symbol of their freedom. These bunch are trigger-happy, arrogant, and poorly trained.
Private citizens who are expert marksmen do not show off, they are either veterans or sports shooters of some sort, both would respect firearms safety. These are the ones that don't go on the news, these are the ones that don't bring out their guns for no good reason.
If you ever played any FPS games, you would know. That in a panick, you will spray and hit almost no one. But when you are well positioned and had good anticipation of enemy approach, you'd have most, if not all, of your shots hit a target. So to speak, the trigger-happy bunch of idiots in the US, they would never make it big on the sports shooting stage nor become military marksmen.
While I would be really surprised if after all the shooting events concluded and none of the US athletes won a medal, I wouldn't count on any medals won by US in shooting being attributed to their freedom of gun ownership.
