- Protection of constitutional rights during police questioning
- Review of police officer conduct and arrest procedures

Violent Crimes Defense

White Collar Crimes and Financial Offenses
White collar crimes such as bank fraud, wire fraud, employee theft and money laundering are often prosecuted in Cook County courts. These cases require a detailed understanding of financial records, investigations, and federal procedures.
Theft-Related Crimes and Retail Theft Defense
Theft-related offenses are among the most commonly charged criminal cases in Chicago and throughout Cook County. While some theft cases involve relatively small amounts of property, others can quickly escalate into serious felony charges depending on the value involved and the surrounding circumstances.
Retail theft, sometimes referred to as shoplifting, is one of the most frequent theft-related charges. These cases often arise from incidents at department stores, grocery stores, or other retail locations, where loss prevention officers detain individuals and contact law enforcement. What may seem like a minor situation can result in criminal charges that carry lasting consequences.
Under Illinois law, retail theft can be charged as either a misdemeanor or a felony. A first-time offense involving a lower dollar amount is typically charged as a Class A misdemeanor, which can still carry penalties including jail time, fines, and a permanent criminal record. However, when the value of the alleged theft exceeds certain thresholds, or when there are prior offenses, the charge may be elevated to a felony. Felony retail theft charges can result in significant penalties, including potential prison time.
The distinction between misdemeanor and felony retail theft is critical. A felony conviction can affect employment opportunities, professional licensing, and future background checks. For that reason, it is important to treat any theft-related charge seriously from the outset.
In many retail theft cases, there may be opportunities to pursue alternatives to a conviction. Depending on the facts of the case and the individual’s background, pretrial diversion programs or deferred prosecution agreements may be available. These options can allow a case to be resolved without a conviction if certain conditions are met, such as completing community service, attending classes, or remaining arrest-free for a period of time.
An experienced criminal defense attorney can evaluate whether a diversion program is appropriate and advocate for a resolution that protects your record whenever possible. Early intervention is often key in securing these types of outcomes.
Andrew M. Weisberg has extensive experience representing clients in theft-related cases, including retail theft and other property offenses. He understands how these cases are handled in Cook County courts and works to identify the best strategy for each client—whether that involves challenging the evidence, negotiating reduced charges, or pursuing a resolution that avoids a conviction altogether.
Protecting Your Constitutional Rights
One of the most critical roles of a criminal defense attorney is protecting your constitutional rights at every stage of the case.
Many individuals do not fully understand what law enforcement officers are permitted to do. Police officers must follow strict legal procedures when conducting searches, making arrests, and questioning suspects.
Andrew M. Weisberg works to ensure:
- Your rights are protected during police encounters
- Evidence obtained illegally is challenged
- The prosecution’s case is carefully examined
- Any violations of your rights are addressed immediately
Even small errors by law enforcement can significantly affect the outcome of a criminal case.
Building a Strong Defense Strategy
A strong defense requires more than just responding to the prosecution’s case. It involves building a comprehensive defense strategy that addresses every aspect of the evidence.
This includes:
- Reviewing police reports and investigative materials
- Locating and interviewing witnesses
- Working with expert witnesses when necessary
- Analyzing forensic and digital evidence
- Identifying weaknesses in the prosecution’s case
In every case, the goal is to demonstrate that the prosecution cannot meet its burden of proof beyond a reasonable doubt.
