Watched with and without r_shownormals 1 and with timescale 0.7, I still find nothing suspicious at 4:40. He simply came out behind a corner and they were there so he shot them down.
hmm, i find especially his mp5 kills dodgy.. his aim is just too perfect.. and then with the deagle he fucks up =/ the WH is not too obvious but the aim with the mp5 is defenitely too weird.
