The debate over "Tasering" has been resurrected by an on-field incident at a Major League Baseball stadium. On Monday, police brought down 17-year-old Steve Consalvi with one of the electrical stun devices after he jumped out of the stands and ran around the field at a Philadelphia Phillies home game. Police have to be vigilant, points out Justin Sablich in the New York Times, because baseball players are "vulnerable to serious attacks by fans"—for instance, a Kansas City Royals coach was assaulted that way in 2002. Granted, Consalvi's field invasion was a stupid stunt, says Craig Calcaterra at NBC Sports. But tasers ought to be a "last resort," not something to be pulled out "without heed to the actual threat"—which wasn't evident in this case. Watch a video of the incident:
