@everyone who say it's lag:
I lag badly (ask my friends) but even I don't do magic like that.
You can't see your own lagg. And also it's a lagg switch not normal lagg.
Why "lagg", not "lag"?
I was in a game once where a guy was killing everyone with one shot of whatever gun he had, and his connection was fine. Hacking isn't new it's just rare.

They deserve to be called out.
you do something wrong, you take the blame for it.
I ran into a guy doing this yesterday, He wasn't doing headshots though, everytime you'd engage him, everything would freeze, he'd kill you and the game would continue as normal until he ran into someone else, he'd freeze up again and win.
Basically if you somehow cacth them unaware you can still kill them, but it's a 85/15 thing in their favor.
