Dennis Nicholl observed the implementation of cellphone signal blockers on trains in Chicago.

He is a silent avenger.

Dennis Nicholl, a financial analyst employed at the University of Illinois Hospital in Chicago, was apprehended last week for realizing the aspiration shared by numerous commuters worldwide: putting an end to disruptive cell phone conversations.

"I think he liked the feeling of being in control of the car," Aaron Robinson, who witnessed Nicol in action, told the Chicago Tribune. "It's kind of like the numbers, 'You young people with cell phones, stay off my lawn. '"

Nicole was apprehended on March 8 in a covert sting operation carried out by the Chicago Police Department, the Chicago Transit Authority, and the Federal Communications Commission. The reason behind his arrest was his involvement in using a jammer to disrupt police radios and impede emergency calls. As a result, he now confronts the possibility of imprisonment and a hefty fine of up to $100,000.

Residents of the Windy City were once again able to make personal calls while on the move, much to the disappointment of many.

The jammer cell phone will be deactivated at this moment. A well-known figure, @AnthonyBialy, shared on Twitter.

New York residents are advocating for the establishment of a local vigilante group to combat jammers within the city.

@dzcman tweeted that taking the NYC bus led them to consider the phone jammer as a valuable investment for maintaining their sanity.

@jammerstore, an online retailer specializing in cell-blockers, has also attempted to capitalize on the demand of New Yorkers to maintain silence among subway riders. They tweeted, "Cell service now available at 6 #NYC stations. Why not consider using a signal jammer diy for uninterrupted travel?" Excessive chatter is unnecessary!

Nicol maintains that his motives solely revolve around seeking peaceful travels.

Charles Lauer, the attorney representing Nichol, informed Tribute that he was distressed about interacting with those in his vicinity. Despite appearing self-centered and self-absorbed, he had no intention of causing harm.
