Case of the Twins

Why does the FBI ask Inspector Strong to provide two people to babysit two witnesses for three-days?
Detective Rage and patrolman Jones are volunteered for the job. The FBI has a leak and uses several decoy cars to leapfrog until the witnesses are delivered. Rage and Jones ride the bus to the University and begin the car jumping. Jones knifes the passenger in the first car and Rage removes the driver. Several cars later the witnesses are in the back seat. A set of blond twin teenage girls.
Rage’s first action is to redress them at the Goodwill thrifty store in an unusual manner. From there to a motel in a seedy part of town to hole up in for three days.

At the motel, an unusual event happens, Jones almost yells, “Stop her, she is taking all her clothes off!” They were too slow. Eventually, this ends up with Rage being tossed up into the ceiling.
They leave the motel three days later in Rage’s jeep and go up Snoqualmie pass to meet with the FBI. They are attached by rockets from an airplane, they are searched for by satellites, and even the FBI wonders where they are. Rage uses her special phone to call a Colonel and tell Inspector Strong what is going on.
She understands the plan and after hiding all night they head east up the pass.

There is a 4th party unknow to anyone that is interested in the four people in Rage’s jeep as they flee Seattle. They are watching them every foot of the way.
In the flatlands of eastern Washington, another attack is being prepared to stop them. Three trucks armed to the teeth are looking for them. Jones might be able to remove two of them but the third is in question.

Will the four people arrive safely at Mountain Home Airforce base in Idaho and can even the Colonel protect them from the people wanting them all dead? What can a set of teenage girls have, or know about quantum anything, to have paid assassins after them?
