Fearing she would consume all the evidence, police used an ASP striking instrument and pepper spray to keep a pregnant woman from eating evidence of what they thought might be marijuana.
Des Moines police arrested Barbra Brown and transported her to Broadlawns Medical Center for treatment of possible marijuana consumption. Police claim they were trying to preserve the evidence.
Ms. Brown managed to eat all of the suspect material with her face buried in the snow while an officer delivered knee blows to her side and sprayed her with mace. She was charged with public consumption for the alcohol she was in possession of.Source
