Many cops were seen rinsing their eyes out with water in the viral clip. According to local reports, the incident took place outside the parliament in Sofia after protestors tried to block the streets.
"Bulgaria is a peaceful country, where protests very rarely go more violent than a bit of pushing. This explains the inexperience of the police with things like pepper spray," explained Jasper Neve, who shared the clip on Twitter.

"Pro tip for protestors: always conduct your protests upwind of the police," laughed one person in the comments section. "Replace 'Bulgarian police' with 'Bungling police'" another quipped.
