Why did Sam Adams and other colonial newspapers portray the incident as "British soldiers killing innocent colonists"?

Because British soldiers killed five and wounded six protesters.

Explanation:

It happened on March 5, 1770. For some time in the streets of Boston, there have been some incidents between the British and the colonists. Citizens resented the new taxes imposed by the British king and parliament. One of the soldiers guarded the location where he kept the king's money. Several protesters gathered there to protest. The soldier hit one of them, and then people hit him with freezes and snow. The soldier fired a shot, soon received reinforcements, and the conflict escalated.

The result was five dead and six wounded colonists. The soldiers were taken into custody shortly afterward. There was intense propaganda on both sides. One of the prominent colonists of S.Adams was at the forefront of propaganda by the colonists. He publicized the brutality of British troops. The period of these protests is linked to the famous slogan that was often called out by the colonists "No taxation without representation" in those days.
