Don't just conclude subjectively based on your perception. No security agent has the mandate to fire at innocent citizens. NLC, TUC, etc has embarked on various protest and no military agency shoot at them, why this IPOB members. Mind you, the so called Emma powerful said "heaven will fall if law enforcement agent hinder their protest" meaning the biafrans protesters are armed. Probably they are trying to embark on a fight with the security agent and they shoot them. Don't be sentimental, reason and interpret objectively.
