A Philadelphia resident arrested for slashing the tires of dozens of cars in his neighborhood, including his own, while talking openly with reporters about what he would do if he caught the alleged vandal, is likely a thrill-seeker, says Temple psychologist Frank Farley, a faculty member at Temple’s College of Education. “Thrill seekers love the attention of the news media because they capture the attention of a much larger audience,” he said.

Joseph Snizavich died of brain cancer and his widow blamed his exposure to chemicals at a Rohm & Haas research facility. But proving a connection between the chemicals and cancer could be difficult, if a judge's ruling this week is any indication. Expert opinions must be delivered with a reasonable degree of scientific certainty, said Edward D. Ohlbaum, a professor at Temple’s Beasley School of Law. "We allow experts to do something that nobody else is able to do, and that is to state an opinion," Ohlbaum said.
