In what appears to be security camera footage from the outside of a bar or small cafe (allegedly in Serbia), we can see an unknown assailant walking swiftly up to the outdoor seating area of this establishment. Several of the customers seem to notice the man walking over as you can see them looking uneasily at him as he approaches. The man walks right up to a gentleman who appears to be wearing a biker style cut / vest and aims his weapon directly at him. It is unclear because there is no audio but it does look like he fired a single shot as the gun appears to recoil after he points it at the men.

The biker and his friend spring up from their seat and chase the man who promptly runs away. They run back inside and the hitman returns and throws something at them which after a few seconds causes the glass door to explode outward. I guess this is what happens when you hire a bargain bin hitman off of Craigslist.
