On a hot July day, fire and police are called to the home of a 55 year old man suffering from heat stroke. Police arrive first and find the man sitting on a bench in his front yard. When the officers approach the man and ask him to give them his cane, he becomes agitated and non-compliant. One officer suddenly grabs the cane away from the man, who screams and suddenly stands up. The man is tased, taken to the ground, beaten and handcuffed. He is transported to the hospital where ER physicians confirm a diagnosis of heat stroke. The man has no criminal history.
