The governor of Massachusetts moved to update the state's voyeurism laws yesterday.
The move came just two days after the state's highest court ruled that a man who took mobile phone photos up the skirts of female subway passengers in Boston was not violating the law as written.
The new law, which takes effect immediately, bans so-called "upskirting" by making it illegal to photograph or videotape the "sexual or other intimate parts" of women or children in public. The law also applies to male victims.
Paedophile Geoffrey Portway will be deported from the US to Britain at the end of his jail sentence, which will be between 18 and 27 years.
Portway, who was born in Spain, possessed more than 20,000 images and videos of children being abused.
In recovered online discussions, he described his home-made dungeon as a place he intended to keep kidnapped children, sexually abuse them, murder them and then eat them.
Briton Geoffrey Portway conspired online with fellow paedophile Michael Arnett to kidnap and abuse children known to them.
In one internet exchange about how to get rid of evidence, they agreed on feeding a child victim's remains to alligators.
Portway repeatedly solicited Arnett to kidnap a child for him, with the intent that Portway would ultimately rape, kill and eat the child in his home-made dungeon.
Arnett, from Kansas, was jailed for 30 years in May.
A Briton living in the United States who plotted to kidnap, rape, kill and eat children has been jailed for nearly 27 years.
Geoffrey Portway was sentenced to 26 years and eight months after US authorities found a dungeon, homemade child-sized coffin, butchering kit and torture tools in his home.
Portway, 40, of Worcester, Massachusetts, chatted online with other paedophiles and solicited their help in kidnapping a child with the intent of raping, killing and eating them.

"Responding agencies continue to investigate the situation," the university said on its website. "Police are sweeping the campus at this time, please continue to stay indoors and remain inside until further notice."
