Fourth Amendment Search and Seizure Issues
Illinois requires probable cause for arrest and reasonable suspicion for investigatory stops. Cook County judges suppress evidence from unconstitutional searches regularly. File motion to quash arrest and suppress evidence - hearing occurs 30-60 days before trial. Prepare exhibits: body cam footage, GPS location data, 911 call recordings. Common violations: warrantless GPS tracking (requires warrant), prolonged traffic stops (20+ minutes without reasonable suspicion), searches exceeding scope of consent. Suppression = dismissal in 60% of drug cases.
Discovery Violations by State
Rule 412 requires State disclose all evidence including exculpatory Brady material. Cook County State's Attorney sometimes delivers discovery late or incompletely. File motion to compel discovery citing specific items missing. Sanctions: continuance at State's expense, suppression of late-disclosed evidence, dismissal for egregious violations. Request: all CPD body cam footage (not just clips State provides), complete lab reports (not summaries), witness criminal backgrounds, impeachment material. Discovery continues until trial - duty to update.
Witness Credibility and Impeachment
Impeach State witnesses with prior inconsistent statements, criminal history, bias, and motive to lie. Illinois allows prior convictions for impeachment if probative value outweighs prejudice. Prepare exhibits: witness prior felony convictions, contradictory police report statements, benefits received (dropped charges, payment). Cross-examine using Rule 238 - refresh recollection with prior statement, then impeach. Cook County juries skeptical of jailhouse informants - success rate: 70% acquittal when informant sole evidence.
Sentencing and Mitigation
Illinois sentencing ranges: Class 4 felony (1-3 years), Class X felony (6-30 years). Prepare mitigation packet: employment letters, educational achievements, military service, mental health/substance abuse treatment, character references, victim impact acknowledgment. Cook County judges grant probation in 40% of Class 4 felonies with strong mitigation. Aggravating factors: criminal history, violence, vulnerable victim. Mitigating factors: age, coercion, mental illness, rehabilitation efforts. Retain mitigation specialist for serious felonies ($3K-8K).
