Surge in Chinese-Made Signal Jammers Prompts DHS Crackdown

The Department of Homeland Security (DHS) has issued a warning about a massive 830% increase in seizures of illegal signal jammers since 2021, primarily originating from China. These devices, illegal in the US and UK, disrupt emergency services and law enforcement communications, facilitating crimes like home invasions and bank robberies. The DHS highlights cases where jammers hampered police responses, and emphasizes the threat to critical infrastructure. While China also bans public use of such jammers, the DHS hopes for cooperation to curb their manufacturing and smuggling.
