I don't see the purpose of it.
The shaped water charge separates the bomb from its detonator without
detonating the bomb. Don't you think that's handy, lew?

How can you fantasize that you Know where the detonator and charge are
located with taking the bomb apart first to see how it is built????
How do you know where it is located in the trunk without taking it out
and looking at it??????

Why can't that blast set off the charge, or trigger the detonator?????

C4 = 18000 feet per second?

All the wires get cut before anything mechanical (like a switch) can move.

What if the detonator is electronic?

More to the point, most such bombs are not set up to trigger if hit with
explosive force. The water blade is strong enough to tear the bomb asunder, but
not strong enough to detonate military explosives.

This is a follow on to a device used to open briefcases thought to contain a
bomb: An extremely powerful water jet generated by a little bit of explosive in
a very heavy steel container filled with water with a nozzle at one end. I
forget the name of the gadget, but there are some videos on YouTube.

One does not use such devices unless it is fairly clear that there is a bomb, or
one is *very* suspicious, as the briefcase or car will be destroyed in the
process. The intent is to recover as much evidence as possible, and to reduce
local damage. Otherwise, just use a shaped charge, or a big wad of C4.
