It sure looks like Baltimore Police Officer Richard Pinheiro planted drugs at a crime scene and if he did, I'm sure it was the first time it's ever happened and he's very sorry if anyone was offended by the mistake that was made.
From Buzzfeed:
In the January 2017 video, Baltimore Police Officer Richard Pinheiro appears to place a bag of pills under some garbage in an alley. He then walks back out to the street, at which point he activates the body camera. But because the cameras are programmed to capture the 30 seconds prior to activation, the officer’s actions before returning from the alley were recorded.
“I’m going to check here,” Pinheiro can be heard saying, before he walks back down the alley. After furrowing around in the trash for a couple seconds, the officer locates the bag inside a soup can and exclaims “yo!” as he holds it up to his two fellow officers, identified to BuzzFeed News by the Maryland public defender's office as officers Jamal Brunson and Jovannes Simonyan.
The defendant who was arrested in connection with the false drug bust was scheduled to face trial this week, Fox Baltimore first reported, but the charges were dropped after the man’s public defender reviewed the video and alerted the prosecutor.
It looks like the other two cops saw officer Pinheiro plant the drugs. I'm sure they are very sorry, too.
