Christmas carolers threatened with arrest!

It seemed like a great idea -- a group of high schoolers taking a merry Christmas flashmob to a retail super-center. However, they didn't expect to be confronted by a modern descendant of the Grinch and Ebeneezer Scrooge. "A shocking video that has gone viral after being posted on Facebook shows a group of caroling kids being thrown out of an Oregon Walmart store and being threatened with a call to the police," writes Dominic Kelly on the website Opposing Views.

The video was first posted on Facebook by a singer's mom, Stacy Kerns. A large group of teens can be seen nervously gathering in front of the checkout counters at a Walmart in Klamath Falls, Oregon. The kids break out into song, belting out Christmas carols and attempting to bring some holiday cheer to the shoppers.

After all, similar Yuletide flashmobs have been well received -- even became international sensations, such as the Philadelphia Opera Company's gathering of 600 singers from schools, churches, community chorales and barbershop quartets at Macy's department store in Philadelphia. Without announcement, they broke out into the Hallelujah Chorus from Handel's Messiah -- to the delight of shoppers and 8.7 million viewers on YouTube.

It inspired imitators worldwide, such as the college kids who brought the Hallelujah Chorus to a shopping mall's food court in Canada. Their YouTube video has been seen by 45 million viewers worldwide.

But not everybody likes Christmas joy -- as moviemaker Kirk Cameron has learned all too well -- as his fun, family-friendly film "Saving Christmas" has been targeted for derision by militant atheists ... and even well-meaning Christians who are convinced celebrating Jesus' birthday is a sin.

In the Oregon Walmart, the high schoolers were rudely interrupted and threatened with arrest. The joyous strains of "Jingle Bells" gave way to memories of "You're a Mean One, Mr. Grinch."

“My daughter and the Henley chorus were doing a flash mob at our Walmart and the co-manager told the kids in the middle of the song to leave it they would call law enforcement,” Kerns wrote on her Facebook video post. “Make this go viral people please!!!!”

Kern’s wishes have come true, as over 3,000 people have now shared her clip on Facebook, resulting in more than 140,000 views. It's also been picked up on YouTube.

"KOBI-TV reports that a spokesperson for the Walmart store has refused to comment but did say that the group wasn’t invited to sing on their private property," writes Kelly. "After the incident in Walmart, the kids were able to successfully bring their Christmas carol flash mob to a Fred Meyer store nearby."
