Hello,
From what I can see there definitely was inappropriate usage of the Nitro Glycerine. It hurt a lot of players not inside the raid, which is a direct breach of the "no crossfire" rule as this was the reason it was implemented. The MP5 Damage seems to be accidental as he's shooting at a player behind you when you turn. I'll definitely speak with him about being more considerate with use of explosives though,thank you.
