Or he could have been like little 12yo Jakey that beat me at my PRS match yesterday in which on one stage we shot targets from 650 to 1080, two shots each for a total of 10 in 90 seconds, (not iron sights obviously). He's unusual in that he's got a Dad that is supporting him in this sport like a BMX dad, but if he sticks with it, he'll likely be pro level by 20, probably earlier.
We don't know shit about fuck when it comes to this shooter, maybe he grabbed some white box ammo from Big-5, or maybe he tested and zero'd his rifle for specific ammo, and had DOPE for such, at this point we just don't know.
As far as the SS missing this location, and if hair hat guy is telling the truth and PoPo really did ignore him, then that stinks of a conspiracy.
At this point I see three possibilities.
1. Lone wolf whacko
2. False flag event sponsored by ?
2. Conspiracy to actually assassinate DJT, sponsored by ?
