A crime is an act or omission of an act that violates public rulesand regulations. Criminal laws in the United States were enacted tomaintain safety and security and ensure the citizens enjoy theirliberties by prohibiting or regulating certain acts. People whoviolate criminal laws face fines, penalties or imprisonment, ordeath, in certain jurisdictions. Criminal laws, just like almost allother laws, originated with common law and its interpretation, andthe development of these interpretations through the years. Specificincidents, in both national and state arena, also drive legislatorsinto formulating new rules and regulations to address theseincidents.

How a crime is defined and what is considered a crime differs fromone state to another's penal code. A state's penal code isaccompanied with enabling rules and regulations. There are alsofederal crimes and federal criminal laws govern these crimes. Fromthe criminal rules and regulations are created law enforcementagencies, such as the police in the state level, and the FederalBureau of Investigation in the federal level, to make sure criminallaws are not violated. The U.S. Constitution, through the Bill ofRights, is the primary law of the land that limits how criminal lawsshould be applied.

A crime is jurisdiction-specific, which means the law where the crimeis committed governs that crime. It follows that jurisdiction remainswhere the crime was committed. One of the issues that make criminallaw a turf only for experts is the differences among criminal laws indifferent jurisdictions. More than 50 states and territories comprisethe United States. Add to that the federal criminal law that governsfederal crimes, and the crimes committed in other jurisdictionsconsidered to be American jurisdictions, such as a ship, an aircarrier, or an embassy. Jurisdiction, thus, becomes a complicatedmatter when a crime in one state may not be a crime in another.Jurisdiction becomes more complicated when a crime is both a statecrime and a federal crime, resulting to overlapping jurisdiction.

Legal research work in criminal cases is exhaustive. Jurisdictiondetermines whether a precedent is binding. An appellate court'sdecision is often the only decision that can create precedents. Thesedecided upon cases are used by criminal law attorneys to boost theirarguments or strengthen their opponent's arguments, so much of theirlegal work is trying to find applicable and strong precedents.

There are numerous crimes, and each crime is specifically definedsuch that the difference between one crime and another may be amatter of a single word. Before an act or an omission is considered acrime, the prosecutor must first establish several elements. Theseelements must be countered upon by the defendant's attorney such thatthe defendant will be found to not have committed the crime or willbe found to have committed a crime with an accompanying lesserpenalty. Arguing against the elements of a crime is a tedious matteras prosecutors and law enforcement agencies, who produce theevidence, are equipped with sophisticated evidence-gatheringmachinery.

Bankruptcy in the United States is governed by the U.S. Bankruptcy Code.Different types of bankruptcy filings are governed by specificsections of the Bankruptcy Code. The types of bankruptcies are: (i)reorganization under Chapter 11 for corporations and individuals,(ii) liquidation under Chapter 7 for corporations and individuals,(iii) Chapter 13 for individuals, and (iv) Chapter 9 for municipalities. Another type of bankruptcy proceeding in the United States are proceedings under Chapter 15 of the Bankruptcy Code, whichallows foreign companies, with assets located in the United States,to seek an injunction of all proceedings that would take their assets from them.

Bankruptcy can be considered a special proceeding, with the creation of aspecial set of courts and judges handling these cases. Corporations,municipalities and individuals who seek protection under the Code aregiven so-called "fresh start" by reorganizing their businesses and finances and ranking their creditors by order of priority. The goal of the Code is to allow a debtor to emerge from bankruptcy with a better business structure, or, in the case ofindividuals, a plan for a better management of finances. Bankruptcy is not adversarial in nature, although adversary proceedings may arise from issues relating to bankruptcy.

Lenders, who are often big banks and financial institutions, are firstpriority in the rank of creditors in bankruptcy proceedings. There are also numerous "small" creditors who need a strong voiceto represent them in bankruptcy proceedings. These small creditorsusually include workers who lost their jobs as a result of a debtor'sfinancial difficulty or who are on the verge of losing their jobswhen a debtor decides to halt their operations. The recent decline inoil prices resulted to the bankruptcy filings of numerous oil and gas companies, resulting to the retrenchment of hundreds of workers. Workers file claims for unpaid wages and benefits and retirees.Workers also seek compensation for damages arising from death orpersonal injury as a result of exposure to toxic minerals orchemicals used by bankrupt companies in the operation of their business. Moreover, small creditors include retirees, whose benefitsare often cut or terminated within the course of the bankruptcy proceeding as a cost-saving strategy for the ailing debtor. Retirees,old but have contributed significantly to the company, join the ranksof lenders to seek to have their benefits reinstated and continued.If not represented by a bankruptcy specialist, these small creditors may find their voices lost among the big corporate lenders.

Divorce,illness, student loan debt, and unpaid mortgages are some of thecommon reasons why individuals seek bankruptcy protection, either under Chapter 11 or Chapter 13. When the individual's bankruptcy proceeding is caused by divorce, the individual debtor needs expert representation by a bankruptcy attorney who is not just knowledgeableof the bankruptcy law but also of divorce law, child support andchild custody. In instances when an individual seeks bankruptcy proceeding as a result of staggering student loan debt or unpaid mortgage, the debtor's attorney also need to match the skills of attorneys representing the student loan provider or the mortgagee, which are often big companies equipped with a legal team ready to quash a creditor.
