Learn History: "The provision pertaining to the use of force can be found in Section III of the Riot Act: "...and that if the persons so unlawfully, riotously and tumultuously assembled, or any of them, shall happen to be killed, maimed or hurt, in the dispersing, seizing or apprehending, or endeavouring to disperse, seize or apprehend them, that then every such justice of the peace, sheriff, under-sheriff, mayor, bailiff, head-officer, high or petty constable, or other peace-officer, and all and singular persons, being aiding and assisting to them, or any of them, shall be free, discharged and indemnified, as well against the King's Majesty, his heirs and successors, as against all and every other person or persons so unlawfully, riotously and tumultuously assembled, that shall happen to be so killed, maimed or hurt, as aforesaid."
Rioting in the streets is never a "Right" guaranteed by the Constitution. People who support such behavior probably have a tingle in their legs whenever the mob beats a cop or breaks a capitalist's windows. I think such suporters have their pulse and breathing rates increase up to a peak and then there is a sudden release of tension just as a rock hits a window.
