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.
For example, under Title 28, Section 547 of the United States Code, U.S. Attorneys have responsibility for the prosecution of criminal cases brought by the federal government, as well as the prosecution and defense of many civil cases where the United States is a party.
