Plain English Breakdown

The official source lists specific systems like fire hydrants and electronic monitoring equipment but does not explicitly define 'critical infrastructure' as a single term; the definition used here summarizes the listed examples.

Stricter Penalties for Damaging Critical Infrastructure

This law makes it a more serious crime to intentionally damage or interfere with public utilities, transportation systems, and emergency services.

What This Bill Does

  • Expands first-degree criminal mischief to include damaging property that causes an actual interruption of public services like power, water, communications, or transportation.
  • Adds second-degree criminal mischief for actions that create a risk of interrupting these essential public systems without necessarily causing a full shutdown.
  • Includes specific protections against damage to fire alarms, police communication systems, emergency dispatch centers, and fire suppression equipment owned by the state or municipalities.
  • Sets first-degree criminal mischief as a Class D felony with potential prison time up to five years or fines up to $5,000.
  • Sets second-degree criminal mischief as a Class A misdemeanor with potential jail time up to 364 days or fines up to $2,000.

Who It Names or Affects

  • People who intentionally damage or tamper with public utilities, transportation modes, power grids, or communication lines.
  • Individuals who harm fire alarm systems, police radios, emergency dispatch centers, or fire hydrants owned by the state or municipalities.

Terms To Know

Criminal Mischief
A crime involving intentional damage to someone else's property without a legal right to do so.
Critical Infrastructure
Essential systems like power, water, transportation, and emergency services that the public relies on daily.
Class D Felony
A serious crime punishable by up to five years in prison or a fine of $5,000.

Limits and Unknowns

  • The law only applies if the person had no reasonable belief that they had the right to damage the property.
  • First-degree charges require actual interruption of service, while second-degree charges apply when there is just a risk of interruption.

The following Fiscal Impact Statement and Bill Analysis are prepared for the benefit of the members of
the General Assembly, solely for purposes of information, summarization and explanation and do not
represent the intent of the General Assembly or either chamber thereof for any purpose. In general,
fiscal impacts are based upon a variety of informational sources, including the analyst’s professional
knowledge. Whenever applicable, agency data is consulted as part of the analysis, however final
products do not necessarily reflect an assessment from any specific department.

Explanation
The bill expands the offenses of criminal mischief in the first and
second degrees , resulting in a potential cost to the Department of
Correction and the Judicial Department for incarceration or probation
and a potential revenue gain to the General Fund from fines. 1 On
average, the marginal cost to the state for incarcerating an offender for
the year is $3,3002 while the average marginal cost for supervision in the
community is less than $6003 each year for adults and $450 each year for
juveniles.
The Out Years

1 Between FY 22 and FY 25, there were a total of 10,818 offenses recorded and $3,000
in fines collected under CGS §§ 53a-115 and 53a-116.
2 Inmate marginal cost is based on increased consumables (e.g., food, clothing, water,
sewage, living supplies, etc.) This does not include a change in staffing costs or utility
expenses because these expenses would only be realized if a unit or facility op ened.
3 Probation marginal cost is based on services provided by private providers and only
includes costs that increase with each additional participant. This does not include a
cost for additional supervision by a probation officer unless a new offense is
anticipated to result in enough additional offenders to require additional probation
officers.
