Military Exercising in Los Angeles

"The exercises are designed to ensure the military's ability to operate in urban environments" why precisely? There are no training facilities available anywhere on a military base so they thought they would just pop over to one of the most highly populated areas in the country.

The military is quietly being deployed on the streets of the United States.

The Posse Comitatus Act is the United States federal law (18 U.S.C. § 1385) that was passed on June 18, 1878, after the end of Reconstruction. Its intent (in concert with the Insurrection Act of 1807) was to limit the powers of local governments and law enforcement agencies from using federal military personnel to enforce the laws of the land. Contrary to popular belief, the Act does not prohibit members of the Army from exercising state law enforcement, police, or peace officer powers that maintain "law and order"; it simply requires that any orders to do so must originate with the United States Constitution or Act of Congress.

Did the people of the United States through their elected representatives in Congress debate and vote on this move?
