Random Searches On Trains

Beginning in July in Boston, "and just in time for the Democratic convention in that city, police largely will put such techno-wizardry aside, and conduct random searches of train and subway passengers - hand checking bags and IDs... The program, however, will need careful tending. While the idea may scare away would-be terrorists, random searches have a low probability of actually nabbing them. Experts say that a random search of 1 in 10 would not even boost security all that much. And such random searches will need constant monitoring to make sure they are truly random and don't become a mask for racial profiling or other abuses."
