Strategies and Considerations for Beating a Controlled Buy Case

Should I Hire a Criminal Defense Lawyer?

Hiring an experienced criminal defense lawyer is strongly recommended if you are facing charges following a controlled drug buy. Navigating the complex criminal justice system on your own is extremely difficult. A knowledgeable attorney can help by:

  • Reviewing and analyzing the prosecutor’s evidence and police reports – Your lawyer will determine the specifics and strength of the case against you.
  • Identifying improper police procedures – If there are issues with how evidence was gathered or handled, your lawyer can file to have evidence thrown out.
  • Interviewing informants or undercover officers – Your lawyer may be able to uncover credibility issues or inconsistencies in their accounts.
  • Negotiating with the prosecutor – Your lawyer can advocate for reduced charges or dismissal if the evidence is weak.
  • Defending you vigorously in court – Your lawyer will ensure your rights are protected and work to create reasonable doubt of guilt.

Do not wait to retain a criminal defense lawyer if you are facing a controlled buy case. The earlier in the process you engage legal counsel, the more effectively they can build your defense strategy. An experienced lawyer’s expertise can make all the difference in these complex cases.

How Can I Challenge the Legality of the Search and Seizure?

A fundamental defense strategy is challenging the legality of the police search, arrest and seizure of evidence. The Fourth Amendment protects citizens against unreasonable searches and seizures – if the police violate your rights, evidence may be excluded. Possible issues to raise include:

  • Lack of probable cause – Police need probable cause to arrest you or search your home or vehicle. If they acted without enough evidence, the resulting search could be deemed illegal.
  • Invalid arrest warrant – Any problems with the warrant, such as misleading information on the affidavit, could invalidate the arrest.
  • Improper frisk or search – Police need specific reasons to believe you are armed and dangerous before conducting a pat down.
  • Consent concerns – If officers ask to “search” without specifying areas, any consent you gave may be considered invalid.
  • Unlawful questioning – Incriminating statements made during a custodial interrogation before Miranda rights were read may be inadmissible.
  • Misconduct during search – Excessive force or destruction of property could lead to exclusion of evidence.

Thoroughly investigating police actions with your attorney is key. If your lawyer can demonstrate constitutional violations, the prosecutor’s case will be seriously undermined.

Should I Challenge the Reliability of the Informant?

In many controlled buy cases, informants play a crucial role, yet their reliability is often questionable. Skilled defense lawyers know that scrutinizing the informant can unravel the prosecution’s case. Issues to raise include:

  • Motive to fabricate – Informants often receive leniency or payment in exchange for cooperating. This motive calls their credibility into question.
  • Background and character – Past criminal history, addiction issues or dishonest acts can be used to undermine an informant’s testimony.
  • Inconsistent statements – Variations in the informant’s accounts to police versus the testimony given in court may indicate fabrication.
  • Contradictory evidence – Other objective evidence that conflicts with the informant’s version of events suggests unreliability.
  • Police coercion – If police pressured the informant to target you, their testimony may lack credibility.
  • Lack of corroborating proof – If the informant’s testimony is the only evidence against you, this makes conviction more difficult.

Informants often have suspect motives. Skilled cross-examination of an informant by an experienced defense lawyer can often expose critical doubts in the prosecution’s case.

Should I Contest Gaps or Inconsistencies in the Chain of Custody?

The prosecution bears the burden of precisely tracking the chain of custody for physical evidence obtained during a controlled purchase. Any gaps or inconsistencies in the record can lead to reasonable doubt about the integrity and authenticity of the evidence. Possible chain of custody challenges include:

  • Unclear tracking record – If the documentation of custody, transfer and storage is incomplete, the evidence may be attacked.
  • Errors in handling – Mistakes like unlabeled evidence, broken seals or contaminated samples suggest sloppy control.
  • Gaps between transfers – Any hand-offs, transport, or storage without documentation breaks the chain.
  • Incorrect testing methods – If the evidence was analyzed improperly or using contaminated tools, results may be invalidated.
  • Altered evidence claims – If there are signs of tampering like inconsistent weights or counts of drugs seized, the defense can raise doubts.

Close scrutiny of how evidence was gathered, documented, stored and tested is key. Any ambiguity surrounding the evidence may lead to it being ruled inadmissible by the judge.

Should I Dispute the Identification of the Suspect?

For a controlled buy conviction, prosecutors must prove beyond a reasonable doubt you are the person who sold drugs to the informant or undercover officer. This identification can often be undermined. As a defense lawyer will explain, flaws in identification create the opportunity for mistaken identity claims, including:

  • Limited observation time – Brief interactions under stressful conditions make accurate ID difficult.
  • Distance and visibility factors – Poor lighting, obstructions and far distances impede identifications.
  • Unconscious transference – Where the officer mistakes someone for a previous suspect based on appearance.
  • Lack of photo lineup – Failure to conduct a proper lineup points to an invalid identification process.
  • Suggestive identification methods – Subtle cues that point to one suspect over another corrupt the ID process.
  • Contradictory witness descriptions – Differences in descriptions from multiple officers or informants indicate flawed identification.

By highlighting problems with how you were identified as the seller, the defense can establish reasonable doubt about one of the key elements of the prosecution’s case.

How Can I Challenge the Credibility of the Police?

It is crucial to remember that police officers are human, and subject to normal errors, false perceptions and even conscious lies. In controlled buy cases, careful defense investigation into the officers involved can uncover:

  • Background credibility issues – Prior disciplinary actions or excessive force complaints point to lack of integrity.
  • Inconsistent or embellished statements – Variations between police reports, interviews and court testimony suggest fabrication.
  • Reliance on assumptions – Officers may have jumped to conclusions rather than sticking to facts.
  • Flawed perceptions during the buy – Stress, expectations and lack of expertise can distort observations.
  • Motivation to close cases at any cost – Pressures to make arrests by any means may encourage misconduct.
  • Racial or other bias – Prejudice may have influenced police handling of suspects who are minorities.

Skilled cross-examination by a defense lawyer can expose police blind spots, assumptions, biases and lies – forcing the prosecutor to defend the credibility of the state’s witnesses.


Facing a controlled buy charge is daunting, but this situation can be overcome by understanding your defense options and hiring an experienced criminal attorney to protect your rights. Methodical examination of the prosecutor’s case and evidence can reveal legal and factual weaknesses.

With an assertive defense challenging issues like unconstitutional searches, unreliable informants and flawed identifications, it is possible to avoid conviction even when the state appears to have a strong case. While every case is different, building an aggressive defense alongside competent legal counsel offers the best chance at success. Don’t lose hope – fight back intelligently against controlled buy allegations.
