I take it you accessed the Jaycor website. Due to some small problems with physics, the 'harpoon' idea cannot work, too bad for them. The inductance of the wire to the harpoon prevents the electric charge from having a risetime quick enough to induce currents in the engine controls that could stop the target car.
Our company is marketing a rocket propelled pulse generator that actually passes under the target vehicle, and has produced over two dozen kills in actual use, although no one has yet tried this in a real police chase. With luck, that may be remedied before fall..
Check out http://www.mcs.net/~ckuecker/nlt.html for our vision..
By the way, Jaycor is the company with the patent on the water cannon. One implementation uses a single stream with a pad on the shooter's foot completing the circuit through the ground. Real bad idea if the shooter lifts that foot while firing..

These exist. Do a search on non-lethal weapons and you will find suppliers. Adjustable force projectile weapons are currently under study by the National Institute of Justive (NIJ).

Remind me not to get in front of you when you are in a 'fun' mood! :)

Definitely - any beat-note interactions that work in air should work in water, with many times the power density possible. Think of three or more ships fitted with these devices ringing in an enemy vessel from outside of visual range, and coordinating their outputs to produce explosive cavitation directly under the hull of the target. Just like the explosion of a torpedo, it could break the ship's keel..
I would like details on the pocket nuclear powered death ray...
