Urban Noise Pollution and the Flight Path of Supersonic Jets

At around 11am yesterday, a military jet flew at low altitude and real fast over the heart of Los Angeles.  You could hear a loud and scary boom as it flew.   There are 8 million people in Los Angeles and to keep this example simple, let's assume that each of us suffered $1 of pain from the surprise and noise.  The Pentagon just caused $8 million dollars in damage. Could this have been avoided?   Why was the plane flying so low?  Why did the plane choose this route? If it had gone 70 miles north, there wouldn't have been anyone there.  If the plane moves at 1000 MPH, then this extra 200 or so miles to loop around LA would added 12 minutes to its flight plan.
