Uh Oh...who left the "cat filter" turned on? Think someone is in trouble? Police in British Columbia, Canada, issued an apology Friday after a cat filter was mistakenly applied to the stream of a news conference about a double murder. When the filter activated, a sergeant with the Royal Canadian Mounted Police suddenly appeared on computer screens with cat ears on her head and whiskers on her face.The cat filter had apparently been on an “automatic setting” and police said Friday on Twitter that they were working to fix the problem -- and a video of the news conference was later made available without the filter.
