The High Bar Des Moines Prosecutors Must Meet

When the government accuses a person of a crime, the government has the burden of proving every element of the charge beyond all reasonable doubt. Every criminal charge has multiple elements. Prosecutors must bring evidence to meet the same standard of proof for everyone. For instance, for the drug charge of simple possession, prosecutors must prove not only that you possessed the drugs, but that you did so knowingly and willingly. If they can't prove that you had it knowingly and willingly, they can't prove their case.

The Role of a Defense Attorney in Iowa Criminal Cases

The role of a criminal defense attorney is to provide zealous representation to the person accused at every stage of the case. The attorney will complete a thorough investigation to uncover any exculpatory evidence or mitigation not known or disclosed by the prosecutor. 

The criminal defense attorney is there to protect the rights of the defendant. Police and prosecutors have various ways of obtaining evidence, from searching your home or car to wiretapping your phones to tracking your cell phone to hacking into your email. These are called "searches." The Fifth Amendment to the Constitution protects you from unreasonable searches and seizures.

Your Des Moines criminal defense lawyer can challenge the constitutionality of the searches and whether police had sufficient probable cause to conduct the search, and had followed the right procedures. If they did not, the evidence might be thrown out by the court, leaving the prosecution with little evidence to pursue their case.

Additionally, your criminal defense lawyer in Des Moines, Iowa, will show the holes in the prosecutor's case, exposing the reasonable doubt. If there is any reasonable doubt in any of the elements of the charge, the jury has no choice but to return a "not guilty" verdict at trial.

Federal and Iowa Criminal Charges

Criminal accusations can be prosecuted under either federal or state criminal laws. Federal laws cover a gamut of different topics. Many federal charges involve financial crimes where the alleged fraud crossed state borders. Federal law enforcement officers also investigate drug crimes, particularly large scale drug trafficking charges. 

Federal criminal accusations are heard in federal court. While the same principles of justice apply, different rules and different procedures apply in federal prosecutions. It is critical for your attorney is experienced in fighting criminal charges in federal court. 

At McCarthy & Hamrock, P.C., our defense lawyers have extensive experience in Iowa federal courts. They are licensed in both the Northern and Southern Districts of Iowa, as well as in the Eighth Circuit Court of Appeals. They have represented many Iowans against federal criminal charges.
