"Connolly surveyed the scene for lone packages and backpacks—anything that could hide another similar device. He saw bags everywhere. With no other options, he pulled out his knife, grabbed a bag, and cut into it. Ripping open potential explosive devices with a knife is not standard procedure. Bomb squads are loaded with sophisticated equipment, and techs normally inspect suspicious packages with a robot, an x-ray machine, or a remotely detonated explosive tool. A so-called hand entry—that Hollywood-style search for the red wire—is almost never done, unless there is no other way to quickly save a life. But that is exactly the situation Connolly and his fellow bomb squad colleagues faced in Boston." - Kevin (aka ThreadKilla)
