On this day 250 years ago, posters went up in Boston signed by “Joyce Junior”, the Chairman of the Committee for Tarring and Feathering. The posters read simply:

Brethren and Fellow Citizens! This is to Certify, That the modern Punishment lately inflicted on the ignoble John Malcolm, was not done by our Order — we reserve that Method for Bringing Villains of greater Consequence to a Sense of Guilt and Infamy.

These posters were a clear indication that the leadership of the Boston Sons of Liberty believed that the mob they had stirred up had gone too far with their brutal treatment of John Malcolm.
