IMPDs tell me that the annual firemen/emt convention here is one that ranks up there with the worst behaved groups. And they hate to have to arrest an idiot because there is an affinity with first responders.
To expand on what Denny said, the electricity is the same, but the effect is completely different.
A drive stun (contact) creates pain, but no physical impairment. You can fight through it without much difficulty if you're dedicated, high, or simply able to move away from the probes.
A dart deployment creates pain, and more of it since its over a wider area, but also physically locks the muscles between the probes up. Shot placement matters A LOT. If I get you in the lower abdomen and upper leg and lock up all your hip muscles, you're falling down. If I get you in the upper back and lower back, you're bending backwards and probably falling down. Regardless of how high you are, how much pain tolerance you have, etc the muscles between the probes are locked up tight as a drum as long as its powered up. The wider the spread and the bigger the muscles between them, the better the effect.
Its also possible to do both. Two probes in and a drive stun, which creates a triangle of muscle lock up and pain.
