When the SRB's are fired, there is no way to shut them down, this is the
major disadvantage of a solid propellant rocket.
A liquid fuel engine can easally shut down by closing the fuel lines: no
fuel, no ignition.

I'm going from memory here, so hopefully I won't pull another
Columbia/Challenger style mix-up. :-)

You can install thrust termination systems on SRB's.

Correct.

However, with the shuttle, it was determined that any thrust termination
system on the SRB's would result in loads so high that the orbiter would be
destroyed anyway.

Correct.
