# Delaware HB 91 (152) — AN ACT TO AMEND TITLE 11 OF THE DELAWARE CODE RELATING TO OFFENSES INVOLVING PROPERTY.

This Act creates a new offense of Aggravated Criminal Mischief with enhanced penalties (class D felony) applicable when an individual knowingly damages or tampers with critical utility infrastructure intending to disrupt utility services. In recent years, the U.S. Department of Homeland Security (DHS) and the FBI have issued repeated warnings about domestic terrorists and extremist groups targeting critical utility infrastructure. Bulletins issued through DHS’ National Terrorism Advisory System in 2022 warned of a heightened threat environment based, in part, on “continued calls for violence directed at U.S. critical infrastructure.” Physical and computerized attacks on electric utility equipment have reached a 10-year high in 2022. Recent attacks in Washington and North Carolina have caused substantial outages and damage to the power grids in both states.
