The person who put the device together obviously didnt know what they were doing, or they used some materials that were not as strong or as sensitive as they hoped they would be. Another possibility is that the detonator, whether it was a timer or a fuse or cell phone, which i think would be a little unlikely in this case, didnt function as designed either. Investigators who inspected the bomb say the bucket, the grocery bag and wires remained intact even after the explosion. That should help authorities find those responsible.
