Why might the british soilders have been justified when they fired on the boston colonists

The British soldiers had every right to start fire at the Boston colonists The British soldiers were being attacked by the colonists. The colonists were throwing harmful objects toward the British people. The British officials were nervous even thought the soldiers were rude to the colonists it gave them no reasoning to endanger the officials or them selves. The colonists named this event the Boston Massacre which took place on March, 1770 and made it seem as thought it was all of the soldiers fault, But in all reality the colonists played a big role leading to the Boston Massacre

Hope it helps :)
