The 48-year-old California man arrested yesterday for making death threats against Speaker of the House Nancy Pelosi has "a history of mental problems," his mother told reporters from San Francisco's ABC News. This history is reflected in previous death threats against others with whom he took umbrage.
Gregory Giusti was convicted in 2004 of criminal threats: The San Mateo District Attorney's office says he was trying to evade the fare on a local commuter train; when the conductor ordered him to get off the train, Giusti began yelling and threatening the conductor's life. As a result, Giusti was sentenced to one year in county jail and three years supervised probation, according to ABC News, which adds that he was also ordered to undergo mental health counseling, and that "a lawsuit filed in February by Hamilton Square Baptist Church in San Francisco ... says Giusti has engaged in and continues to engage in a campaign of harassment against people at the church."
Giusti has a record of dodging public-transit fares and causing disruptions. He was sued by the Bay Area Rapid Transit system in 1996. According to ABC News, he also has two convictions in San Francisco for welfare fraud and petty theft from 1992.
