Possession of criminal tools is a charge brought when someone has an object they intend to use to commit a crime, even if the crime never happens. The item itself is often legal to own. What makes it a crime is the intent behind having it. Penalties track the seriousness of the planned offense: a misdemeanor-level charge can mean up to 180 days in jail, a felony-level charge can mean years in prison, and certain federal versions carry up to 15 years for a first offense.
What Counts as a Criminal Tool
A criminal tool is any object, substance, device, or piece of equipment possessed with the intent to use it in committing a crime. The category is written broadly on purpose. A crowbar, a laptop, a set of lock picks, a printer, a flashlight, a digital scale, a glass cutter, blank card stock with a magnetic stripe, a pill press, a cloned key fob. Any of these can qualify under the right circumstances, and none of them has to be illegal to own.
The legal question is never really about the object. A bolt cutter in a maintenance worker’s truck is a tool of the trade. The same bolt cutter in a car parked behind a fenced warehouse at 2 a.m., alongside gloves and a duffel bag, looks like preparation for a break-in. The statute is designed to reach the second situation without criminalizing the first.
Intent Is the Whole Case
Owning an item is not enough. The prosecution has to prove that the person possessed it with the specific purpose of using it to commit a crime. Most of these cases are won or lost on this element.
State statutes typically identify categories of evidence that create a legal presumption of criminal purpose. Items specially designed or adapted for criminal activity carry the strongest presumption. A credit card skimmer has essentially no legitimate purpose for a private individual. A slim jim in the hands of someone who is not a locksmith or a tow operator is similar. When the object itself points toward illegal use, the burden effectively shifts to the defendant to offer an innocent explanation.
For everyday objects, the prosecution builds intent from circumstances. Location, timing, the combination of items found together, the person’s behavior, prior history, statements to others, internet search history, and the absence of a plausible lawful reason all factor in. Someone caught near a closed business at night carrying a glass cutter, tape, and a bag is in a very different position than someone with the same glass cutter in a toolbox at home. Prosecutors build the intent case one detail at a time.
You Don’t Have to Be Holding It
The law recognizes two kinds of possession, and the second one catches people off guard.
- Actual possession: the item is on your person, in your hand, in a pocket, or in a bag you are carrying.
- Constructive possession: the item is somewhere else, but you know about it and have the ability to control it. The trunk of your car, a locker you rent, a closet in your apartment.
Constructive possession requires both knowledge and control. A court will not convict someone who genuinely did not know an item existed in a space they happened to occupy. This matters most in shared cars and shared apartments. The prosecution has to connect the specific person to the specific item, not just show the item was nearby.
Penalties
The severity of the charge almost always tracks the seriousness of the crime the person intended to commit. That sliding scale produces a wide range of outcomes.
Misdemeanor Level
When the intended crime is itself a misdemeanor, the tools charge is usually a misdemeanor too. Penalties generally include up to 180 days in jail and fines that can reach $1,000 or more depending on the jurisdiction. First-time offenders often receive probation in place of or alongside jail time.
Felony Level
When the intended crime is a felony, the tools charge becomes a felony. Prison exposure commonly runs from six months to several years, with higher fines. Some states treat felony-level criminal tools possession as a lower-tier felony across the board; others scale it to match the planned offense more precisely.
Federal Charges
Certain tools trigger federal jurisdiction, especially anything involving access devices. Possessing device-making equipment with intent to defraud carries up to 15 years in federal prison for a first offense and up to 20 years for a subsequent offense, plus forfeiture of any property used or intended for use in the crime.1Office of the Law Revision Counsel. 18 USC 1029 – Fraud and Related Activity in Connection With Access Devices Federal law also reaches scanning receivers designed to intercept electronic communications and hardware or software configured to alter telecommunications identifying information, with similar maximum penalties.
One boundary worth knowing: federal computer fraud law does not criminalize the mere possession of hacking software or penetration testing tools. The federal statute targets unauthorized access, intentional damage, and trafficking in passwords rather than simply having software on a hard drive.2Office of the Law Revision Counsel. 18 USC 1030 – Fraud and Related Activity in Connection With Computers State laws vary, and some are broader in the digital context.
Being Charged With the Tools and the Crime
Prosecutors routinely charge possession of criminal tools alongside the completed or attempted offense. Someone who breaks into a building and is caught with burglary tools can face a burglary charge and a separate criminal tools charge. The two offenses address different conduct. One punishes the break-in; the other punishes the preparation. Whether both convictions can stand at sentencing depends on the jurisdiction’s rules about merging related offenses, but being charged with both at once is standard practice.
That stacking is one reason the tools charge carries real weight even when the underlying conduct looks minor. An additional count means additional penalties, a longer record, and more leverage for prosecutors during plea negotiations.
Defenses That Work
Because the charge turns on intent rather than the nature of the object, there are several meaningful lines of defense.
Legitimate purpose. The most direct defense is that the items had a lawful use. A locksmith carrying lock picks, a hobbyist with electronics equipment, or a contractor with cutting tools can explain the possession without any reference to a criminal plan. Strength depends on fit. A licensed locksmith stopped during business hours with picks in a branded work van has an airtight story. Someone with no connection to the trade carrying the same picks outside a closed jewelry store at midnight does not.
Lack of knowledge. In constructive possession cases, the defendant can argue they did not know the items were present. A borrowed car with tools hidden in the trunk is a classic example. The prosecution has to prove both knowledge and control, so reasonable doubt about either element can defeat the charge.
Challenging the search. The Fourth Amendment protects against unreasonable searches and seizures. If police discovered the tools during an illegal search, defense counsel can move to suppress that evidence. When the motion succeeds, the prosecution loses its physical evidence, which usually collapses the case. Common grounds include searches without a warrant or probable cause, warrants based on false information, and searches that exceeded the scope of a valid warrant.3Congress.gov. Fourth Amendment – Standing to Suppress Illegal Evidence
Insufficient evidence of intent. Even when the tools are legally discovered and clearly belong to the defendant, the prosecution still has to prove criminal intent beyond a reasonable doubt. If the only evidence is the items themselves, and none of them are specially designed for criminal use, prosecutors face a steep climb. Courts have reversed convictions where the connection between the tools and any planned crime was too speculative.
Constitutional challenges. Because the statutes are intentionally broad, defendants sometimes attack them as unconstitutionally vague or overbroad, arguing the law fails to give ordinary people fair notice of what is prohibited. These challenges succeed most often when prosecutors stretch the definition of “criminal tool” to cover everyday objects without strong circumstantial evidence of intent.
What a Conviction Costs Beyond the Sentence
The jail time and fines are only part of the picture. A conviction leaves a record that reaches into employment, housing, and licensing.
- Employment: roughly 87% of employers run background checks, and formerly incarcerated individuals earn approximately 40% less annually compared to peers without records.4Office of Justice Programs. Collateral Consequences of Criminal Convictions Judicial Bench Book
- Housing: federal law allows local housing authorities to deny public housing based on criminal activity, and private landlords routinely screen records.
- Professional licensing: state boards in healthcare, real estate, education, and finance can deny, suspend, or revoke a license based on a conviction, particularly one tied to dishonesty or the functions of the profession.
- Firearms: a felony-level conviction triggers a federal prohibition on possessing firearms. Misdemeanor convictions generally do not, though some states impose additional restrictions.
Expungement or sealing is available in many states for certain criminal tools convictions, particularly at the misdemeanor level. Eligibility rules, waiting periods, and filing fees vary. Court filing fees for expungement petitions typically range from $30 to over $200, not counting attorney costs. Clearing the record is worth pursuing because it removes or limits the visibility of the conviction on background checks, which directly addresses the employment and housing barriers above.
