The Boston Massacre
British troops came to Boston to guard against violence. Boston reacted with a boycott of British goods so the British moved all shipping to Salem. This resulted in an economic downturn and less tax money available TO PAY THE TROOPS. To make ends meet, British soldiers are taking odd jobs in town. This has led to a close intermingling of the guards with the Boston citizens, especially in taverns. Fights break out regularly and those incidents are scandalized in the newspapers. Recently, an 11-year-old-boy was killed by a customs official, so Boston is in an uproar when a young apprentice named Edward Garrick tries to collect an overdue bill at the customs office. After an exchange of insults, Private Hugh White leaves his guard post and strikes Edward on the head for his insolence. Henry Knox, a bookseller and future General of the Revolution, reminds White that if he kills the boy it means a murder charge. A mob forms so Captain Preston reinforces White with armed troops. The Captain has no intention of ordering his men to fire, but someone hits Private Montgomery with a rock, causing him to drop his musket. He picks it up, shouts at the mob and fires. Someone swings a club at Captain Preston. In a few quick seconds, four protestors lie dead in the street. Many others are wounded and some will die later. Captain Preston and his men are arrested for murder and Boston is crying for their blood!   
The Ferguson Rifle, a Radical New Method for Mayhem
A rifle took ten minutes to load... until now. Major Patrick Ferguson has reworked an earlier design so that his new BREECH LOADING rifle can load and fire 6 times a minute! It is faster than a smooth-bore musket which can fire 2 times a minute and it is more accurate due to the rifling of the bore. One can also load it from a semi-prone position. Ferguson won't be issued a patent until 1776 when the British Army will order 100 rifles in order to put down the American Revolution. (FYI... it was just an experiment. It didn't help.)  
I Know! Let's Call It Rubber!
"Rubber" gets its name when the scientist, Joseph Priestley, realizes that the bouncy material can "rub off" pencil marks. Scientists have been looking for ways to use rubber other than as a ball. (How about as a HOSE!) Rubber has been a novelty item since the Middle Ages when it was introduced to Europe by the Aztecs. Joseph Priestley is the same guy who discovered oxygen, and he made his name when he invented carbonated beverages.

He recovered his weapon, and was thought to angrily shout 'Damn you, fire!', then discharged it into the crowd although no command was given. Palmes swung his cudgel first at Montgomery, hitting his arm, and then at Preston. He narrowly missed Preston's head, striking him on the arm instead.”

But it was too late. Four Bostonians lay dead, and several others were badly wounded, one of whom died early the next morning. For Boston, what locals would call the Boston Massacre immediately became that generation's Kent State shooting.”

A rate of fire of 6 shots per minute or better was easily possible for a well-drilled shooter, and this from a weapon with the accuracy of a rifle.”
