So while spectating a player to see if he is cheating or not i saw him passing through 2 enemy claymores. Such claymores were perfect positioned to his direction so he should take the damage but it does not occur nor on the following seconds
I would ask for your opinion. Is there some possibility of cheating or it is just some sort of spectator mode bug? Thanks in advance!

since im just asking for some opinion and it's not a report i'm hiding the player's name

Seems normal to me. He didn't get in to the door when the claymore explosion happened, I think.

Seeing the footage i doubt the first one was a claymore (or a correctly placed one).

If there was a claymore facing the door you would have seen the claymore wires. I don't see these on the video. So or the claymore was placed the wrong way or it was some other kind of explosive. It could also be that i got bugged out cuz of the wrong positioning. The second claymore got destroyed by an BTW law at 00:11. 

Claymores do sometimes bug out, you can also jump over the wires or survive them with certain perks (eventhough they will badly damage you).
