Why not HOT tar and feathers.
Or, did you mean “Coal tar?” If there is such a thing.
Subjects or citizens have been lied to since this whole thing started
It is for us to investigate or sit and stew.
“Since prehistoric times wood tar has been used as a water repellent coating for boats, ships, sails, and roofs.”
“[Wood] Tar was once used for public humiliation, known as tarring and feathering. By pouring hot wood tar onto somebody’s bare skin and waiting for it to cool, they would remain stuck in one position. From there, people would attach feathers to the tar, which would remain stuck on the tarred person for the duration of the punishment. That person would then become a public example for the rest of the day.”
“Coal tar was formerly one of the products of gasworks. Tar made from coal or petroleum is considered toxic and carcinogenic because of its high benzene content”

Hot tar would be murder. We have never used hot tar. It was used in battle not long ago.
Cold tar has been around for centuries. Also known as roof patch or mastic.
