The man shot and killed by Boston police on Tuesday was plotting to behead a police officer, law enforcement officials tell the Boston Globe. “We believe the intent was to behead a police officer,” an official told the Globe of the victim, who's been identified as Usaama Rahim. “We knew the plot had to be stopped. They were planning to take action Tuesday." The 26-year-old man was shot in front of a CVS on Washington Street in the Roslindale neighborhood of Boston by two police officers when he came at them with a knife, say police. A second man, David Wright, was arrested on Tuesday evening in Everett in connection with the case. He is set to appear in court on Wednesday afternoon. http://www.mashable.com LIKE us on FACEBOOK: / mashable.video FOLLOW us on TWITTER: / mashablevideo FOLLOW us on TUMBLR: / mashable FOLLOW our INSTAGRAM: / mashable JOIN our circle on GOOGLE PLUS: http://plus.google.com/+Mashable Subscribe!: http://bit.ly/1ko5eNd Mashable is the leading independent news site for all things tech, social media, and internet culture. / mashable
