One of the stories we're developing for tomorrow's newspaper is whether BART should conduct random searches as a precautionary move to prevent events like what we're seeing in London. The city of New York announced today that police will begin conducting random searches of packages and backpacks carried by people entering New York City subways. The BART board is not, right now, considering a similar move. Other major cities, like Boston, are contemplating this type of move. We'll be asking readers to sound off on the issue through a discussion board at contracostatimes.com. Feel free to weigh in by posting on this blog or on our discussion board.
