It's just past midnight on a freezing Saturday night in Washington, D.C.
In the last hour, five ambulances have arrived at the emergency room where I work. A sixth pulls up.
The paramedics wheel out a stretcher carrying a man, 73, strapped to a hard board, a precaution in case his spine is fractured. There's blood around his neck brace and a strong smell of urine.
"We found him by his bed," a paramedic tells me. The patient told the paramedics he slipped. "Reports back pain and some cuts and bruises," one of them adds.
