What followed struck a telling blow to the Prime Minister’s dream highway project in Bihar and Jharkhand as professional engineers such as Kumar still struggle to exorcise the ghost of January 30. The camp, Kumar remembers, was buzzing with activity that day. Workers were trooping in, trucks and tippers lining up for the night shift while engineers were taking stock of the day’s progress and planning for the night ahead. ‘‘As the senior project engineer, I was getting ready to conduct the meeting when I heard gunshots.
