Have you ever wondered how criminal defense attorneys actually get felony cases dismissed?
It doesn’t happen by luck. It doesn’t happen by pleading. And it definitely doesn’t happen by waiting things out.
In Oklahoma, felony cases are dismissed when defense attorneys uncover violations of constitutional rights, challenge illegal police conduct, and force prosecutors to prove they followed the law from the very beginning.
I’m John Cannon, a criminal defense attorney and former prosecutor. In this article, I’ll break down the exact process we use to seek dismissals in every felony case we handle, starting with the most powerful legal tool in criminal defense: suppression of evidence.
The First Step: Gathering All the Evidence
Every potential dismissal starts with evidence.
That means all evidence, not just what law enforcement chooses to turn over.
A proper defense investigation includes:
Police reports
Body-cam and dash-cam footage
Search warrants and affidavits
Dispatch logs
Surveillance video
Statements from witnesses
Evidence gathered by an independent defense investigator
Once we have everything, we ask one critical question:
Did law enforcement follow the law?
Identifying Police Mistakes and Rights Violations
Police officers must follow strict constitutional rules. When they don’t, evidence can be excluded — and cases can collapse.
Common violations include:
Illegal traffic stops
Unlawful searches of vehicles or homes
Detaining someone too long without cause
Improper use of drug dogs
Stops based on race, gender, or profiling
Searches without valid consent or a warrant
If officers crossed the line, that opens the door to suppression of evidence.
What Is Suppression of Evidence?
Suppression of evidence is a legal motion asking the court to keep illegally obtained evidence out of the case.
In simple terms:
If police violated your rights
And that violation produced key evidence
The government may be barred from using it
If the prosecution loses critical evidence, they often cannot proceed at all — and the case is dismissed.
Real Case Example: Federal Felony Dismissed
We recently represented a client charged in federal court with:
Aggravated drug trafficking
Drug conspiracy
Facing 10+ years in federal prison
After reviewing the evidence, we discovered:
The traffic stop was improper
The detention was unreasonably long
The drug dog did not lawfully alert
The stop was motivated by racial profiling
At the suppression hearing, the officer admitted under oath that the stop occurred because the occupants were Black.
That is never a legal basis for a stop.
The judge granted the motion to suppress.
The U.S. Attorney’s Office had no admissible evidence left.
The case was dismissed.
Why Suppression Hearings Often End Cases Early
Suppression hearings are risky for prosecutors.
Why?
Officers testify under oath
New facts can emerge
Credibility can be destroyed
Judges remember losses
Bad rulings affect future cases
Prosecutors often choose to:
Dismiss charges
Reduce charges
Offer significantly better plea terms
All to avoid losing a suppression hearing or trial.
Why Felony Dismissals Happen Before Trial
Both sides understand the stakes.
If:
A defense attorney loses at trial → the client loses freedom
A prosecutor loses at trial → their credibility and office reputation suffer
That’s why strong suppression arguments frequently lead to dismissals or reduced consequences long before a jury is ever seated.
The Human Side of Getting a Case Dismissed
Legal arguments matter — but people matter too.
When prosecutors review a case, they often see:
A name
A charge
A prior record (if any)
Defense attorneys must show:
Who the client really is
Their family responsibilities
Employment history
Rehabilitation efforts
A plan for life beyond the case
At Cannon & Associates, we work with clients and families to present a complete picture, not just legal arguments.
That combination — legal leverage + human story — often leads to dismissals or far better outcomes.
Why Rights Violations Matter More Than the Allegation
Here’s a fundamental principle of criminal defense:
If law enforcement violates constitutional rights, it is more important that a person goes free than that illegal conduct is rewarded.
That principle protects everyone.
Suppressing evidence isn’t a loophole — it’s the enforcement of constitutional limits on government power.
Final Thoughts: Dismissals Are Built, Not Hoped For
Felony cases don’t get dismissed by chance.
They get dismissed when defense attorneys:
Investigate aggressively
Challenge illegal police conduct
File suppression motions
Force accountability
Tell the client’s full story
If your rights were violated, that may be the strongest path to freedom.
