But that doesn't mean it was unbiased - far from it. Presses were commonly used to print propaganda. Every newspaper had its slant. Thank goodness that doesn't happen nowadays. Anyway, part of what made the Boston Massacre such a turning point were reprints of Paul Revere's woodcut - it showed organized British soldiers in full formation firing point-blank at an innocent crowd. A shocking image, which enraged the people and fuelled their hatred of the British. Completely made-up, of course, but what did that matter? The public is there to be manipulated.
