From Yahoo News:
A man was gravely wounded in a gun battle with police in Ferguson, Missouri on Sunday night after a day of peaceful rallies to mark the fatal shooting of an unarmed black teenager by a white officer one year ago. Several volleys of gunshots rang out as police in riot gear tried to disperse demonstrators blocking traffic and smashing storefront windows along a street that was a flashpoint of last year's unrest in the St. Louis suburb after Michael Brown, 18, was slain. Police later said the gunfire began with two groups of agitators apparently shooting at each other.

Anniversary commemorations had begun hours earlier with a peaceful march through the St. Louis suburb. The scene changed dramatically after dark. Dozens of protesters converged on West Florissant Avenue, which bore the brunt of last summer's rioting, and chanted: "Shut it down" in the midst of a severe thunderstorm.

By coincidence, I was recently at the Boston Tea Party museum in Boston, which covered an event that happened only a few years later at Boston.
They had something of a reenactment. The leaders were careful to add every so often "and by the way, remember that this is treason".
If the analogy to the Revolutionary War that you make is correct, all the protestors should be hanged for treason, assuming they don't succeed in overthrowing the government.
