For bacterial pneumonia, doctors prescribe antibiotics. Viral pneumonia doesn't respond to antibiotics, so treatment may be limited to rest and fluids. In fact, getting enough fluids is vital to fight the dehydration from rapid breathing and fever that's often a side effect of pneumonia.
The defense attorney's role is of paramount importance in almost every criminal case. From arraignment to sentencing: investigating facts and evidence, cross-examining government witnesses, objecting to improper questions and evidence, and presenting any legal defenses.
The system also provides for every citizen to be represented in court by an attorney. If an accused person is unable to pay for his own defense attorney, the court assigns a public defender to him. The role of both a public defender and a private defense attorney is the same.
