This fighter simply holds his AK at about chest height and marches, firing, through a door with enemy inside. Perhaps inspired by movies or video games, who knows.
Police in this video clear a house room by room with a mix of best practice and sloppier methods (in particular brazenly opening doors and sticking their head or guns in) before they are confronted with a man who attacks with a knife. Luckily, in the last room they did not approach the closet door immediately and open it, allowing enough of a reactionary gap to avoid being stabbed.
A man with two knives attempts to stab a police officer. Due to sheer luck, he did not attempt to stab the officer anywhere except the stab-proof vest he was wearing.
A taser was deployed very little practical effect.
Combined videos above and police dashcam:
The gunman fired 9 rounds from his 40 calibre firearm. Two officers fired approximately 26 rounds from their firearms, and the suspect was struck 18 times.
The aftermath of the gunfight is captured by a motorist driving past. The incredible footage shows police taking cover, assisting victims, and one cop helping another who had been shot. 4 civilians, the gunman and 1 officer were injured in the shootout. The gunman did not survive.
