Katy Perry's 'Roar' Used By Police To Halt Protesters

Dolly Parton and the Bee Gees also made the list.

Thousands of Filipinos gathered in Manila on Thursday (Nov. 18) in protest of the Asia-Pacific Economic Cooperation's (APEC) free-trade agenda, which protesters claim favors protection of large corporations over the rights of poor, working-class citizens.

As crowds became more aggressive outside the APEC summit where 21 world leaders were gathered, police used a different strategy -- one that didn't involve the use of riot shields, water canons or wood batons that proved ineffective.

They began blasting a pop-fueled playlist from their speakers.

According to ABC, in an attempt to appeal to a nation of music lovers, police led the musical dispersion tactic with Katy Perry's "Roar," followed by other hits like David Guetta's "Sexy Bitch," Dolly Parton's "Islands In The Stream" and the Bee Gee's "How Deep Is Your Love."

Officers even began tapping their batons to their riot shields in time with the music's rhythm.

While the technique proved effective at keeping the situation from turning violent, protesters were angered at the disrespectful response from authorities.

"We understand the seriousness of the issues," Metro Manila police spokeswoman chief inspector Kimberly Gonzales told ABC. "We don't mean to insult people."

No injuries or arrests have been reported.
